Affected Products:
SUSE Linux Enterprise Server 12-SP2-BCL
______________________________________________________________________________
An update that solves 36 vulnerabilities and has 7 fixes is now available.
Description:
The SUSE Linux Enterprise 12 SP2 LTSS kernel was updated to receive various
security and bugfixes.
The following security bugs were fixed:
o Unprivileged BPF has been disabled by default to reduce attack surface as
too many security issues have happened in the past (jsc#SLE-22573)
You can reenable via systemctl setting /proc/sys/kernel/
unprivileged_bpf_disabled to 0. (kernel.unprivileged_bpf_disabled = 0)
o CVE-2017-5753: Systems with microprocessors utilizing speculative execution
and branch prediction may have allowed unauthorized disclosure of
information to an attacker with local user access via a side-channel
analysis (bnc#1068032). Additional spectrev1 fixes were added to the eBPF
code.
o CVE-2018-13405: The inode_init_owner function in fs/inode.c allowed local
users to create files with an unintended group ownership, in a scenario
where a directory is SGID to a certain group and is writable by a user who
is not a member of that group. Here, the non-member can trigger creation of
a plain file whose group ownership is that group. The intended behavior was
that the non-member can trigger creation of a directory (but not a plain
file) whose group ownership is that group. The non-member can escalate
privileges by making the plain file executable and SGID (bnc#1087082 bnc#
1100416 bnc#1129735).
o CVE-2018-16882: A use-after-free issue was found in the way the KVM
hypervisor processed posted interrupts when nested(=1) virtualization is
enabled. In nested_get_vmcs12_pages(), in case of an error while processing
posted interrupt address, it unmaps the 'pi_desc_page' without resetting
'pi_desc' descriptor address, which is later used in pi_test_and_clear_on
(). A guest user/process could use this flaw to crash the host kernel
resulting in DoS or potentially gain privileged access to a system. Kernel
versions and are vulnerable (bnc#1119934).
o CVE-2020-0429: In l2tp_session_delete and related functions of l2tp_core.c,
there is possible memory corruption due to a use after free. This could
lead to local escalation of privilege with System execution privileges
needed. User interaction is not needed for exploitation (bnc#1176724).
o CVE-2020-12655: An issue was discovered in xfs_agf_verify in fs/xfs/libxfs/
xfs_alloc.c in the Linux kernel Attackers may trigger a sync of excessive
duration via an XFS v5 image with crafted metadata, aka CID-d0c7feaf8767
(bnc#1171217).
o CVE-2020-14305: An out-of-bounds memory write flaw was found in how the
Linux kernel's Voice Over IP H.323 connection tracking functionality
handled connections on ipv6 port 1720. This flaw allowed an unauthenticated
remote user to crash the system, causing a denial of service. The highest
threat from this vulnerability is to confidentiality, integrity, as well as
system availability (bnc#1173346).
o CVE-2020-3702: Specifically timed and handcrafted traffic can cause
internal errors in a WLAN device that lead to improper layer 2 Wi-Fi
encryption with a consequent possibility of information disclosure over the
air for a discrete set of traffic (bnc#1191193).
o CVE-2021-20265: A flaw was found in the way memory resources were freed in
the unix_stream_recvmsg function in the Linux kernel when a signal was
pending. This flaw allowed an unprivileged local user to crash the system
by exhausting available memory. The highest threat from this vulnerability
is to system availability (bnc#1183089).
o CVE-2021-31916: An out-of-bounds (OOB) memory write flaw was found in
list_devices in drivers/md/dm-ioctl.c in the Multi-device driver module in
the Linux kernel A bound check failure allowed an attacker with special
user (CAP_SYS_ADMIN) privilege to gain access to out-of-bounds memory
leading to a system crash or a leak of internal kernel information. The
highest threat from this vulnerability is to system availability (bnc#
1192781).
o CVE-2021-33033: The Linux kernel has a use-after-free in cipso_v4_genopt in
net/ipv4/cipso_ipv4.c because the CIPSO and CALIPSO refcounting for the DOI
definitions is mishandled, aka CID-ad5d07f4a9cd. This leads to writing an
arbitrary value (bnc#1186109 bnc#1186390 bnc#1188876).
o CVE-2021-34556: In the Linux kernel through 5.13.7, an unprivileged BPF
program can obtain sensitive information from kernel memory via a
Speculative Store Bypass side-channel attack because the protection
mechanism neglects the possibility of uninitialized memory locations on the
BPF stack (bnc#1188983).
o CVE-2021-34981: Fixed file refcounting in cmtp when cmtp_attach_device
fails (bsc#1191961).
o CVE-2021-3542: Fixed heap buffer overflow in firedtv driver (bsc#1186063).
o CVE-2021-35477: In the Linux kernel through 5.13.7, an unprivileged BPF
program can obtain sensitive information from kernel memory via a
Speculative Store Bypass side-channel attack because a certain preempting
store operation did not necessarily occur before a store operation that has
an attacker-controlled value (bnc#1188985).
o CVE-2021-3640: Fixed a Use-After-Free vulnerability in function
sco_sock_sendmsg() in the bluetooth stack (bsc#1188172).
o CVE-2021-3653: A flaw was found in the KVM's AMD code for supporting SVM
nested virtualization. The flaw occurs when processing the VMCB (virtual
machine control block) provided by the L1 guest to spawn/handle a nested
guest (L2). Due to improper validation of the "int_ctl" field, this issue
could allow a malicious L1 to enable AVIC support (Advanced Virtual
Interrupt Controller) for the L2 guest. As a result, the L2 guest would be
allowed to read/write physical pages of the host, resulting in a crash of
the entire system, leak of sensitive data or potential guest-to-host
escape. (bnc#1189399).
o CVE-2021-3655: A vulnerability was found in the Linux kernel in versions
prior to v5.14-rc1. Missing size validations on inbound SCTP packets may
have allowed the kernel to read uninitialized memory (bnc#1188563).
o CVE-2021-3659: Fixed a NULL pointer dereference in llsec_key_alloc() in net
/mac802154/llsec.c (bsc#1188876).
o CVE-2021-3679: A lack of CPU resource in the tracing module functionality
was found in the way user uses trace ring buffer in a specific way. Only
privileged local users (with CAP_SYS_ADMIN capability) could use this flaw
to starve the resources causing denial of service (bnc#1189057).
o CVE-2021-37159: hso_free_net_device in drivers/net/usb/hso.c in the Linux
kernel calls unregister_netdev without checking for the NETREG_REGISTERED
state, leading to a use-after-free and a double free (bnc#1188601).
o CVE-2021-3715: Fixed a use-after-free in route4_change() in net/sched/
cls_route.c (bsc#1190349).
o CVE-2021-3732: Mounting overlayfs inside an unprivileged user namespace can
reveal files (bsc#1189706).
o CVE-2021-3752: Fixed a use after free vulnerability in the Linux kernel's
bluetooth module. (bsc#1190023)
o CVE-2021-3753: Fixed race out-of-bounds in virtual terminal handling (bsc#
1190025).
o CVE-2021-37576: arch/powerpc/kvm/book3s_rtas.c on the powerpc platform
allowed KVM guest OS users to cause host OS memory corruption via
rtas_args.nargs, aka CID-f62f3c20647e (bnc#1188838 bnc#1190276).
o CVE-2021-3760: Fixed a use-after-free vulnerability with the ndev->
rf_conn_info object (bsc#1190067).
o CVE-2021-3772: Fixed sctp vtag check in sctp_sf_ootb (bsc#1190351).
o CVE-2021-38160: Data corruption or loss could be triggered by an untrusted
device that supplies a buf->len value exceeding the buffer size in drivers/
char/virtio_console.c (bsc#1190117)
o CVE-2021-38198: arch/x86/kvm/mmu/paging_tmpl.h incorrectly computed the
access permissions of a shadow page, leading to a missing guest protection
page fault (bnc#1189262).
o CVE-2021-38204: drivers/usb/host/max3421-hcd.c allowed physically proximate
attackers to cause a denial of service (use-after-free and panic) by
removing a MAX-3421 USB device in certain situations (bnc#1189291).
o CVE-2021-3896: Fixed a array-index-out-bounds in detach_capi_ctr in drivers
/isdn/capi/kcapi.c (bsc#1191958).
o CVE-2021-40490: A race condition was discovered in
ext4_write_inline_data_end in fs/ext4/inline.c in the ext4 subsystem in the
Linux kernel (bnc#1190159)
o CVE-2021-42008: The decode_data function in drivers/net/hamradio/6pack.c in
the Linux kernel has a slab out-of-bounds write. Input from a process that
has the CAP_NET_ADMIN capability can lead to root access (bnc#1191315).
o CVE-2021-42739: The firewire subsystem in the Linux kernel has a buffer
overflow related to drivers/media/firewire/firedtv-avc.c and drivers/media/
firewire/firedtv-ci.c, because avc_ca_pmt mishandled bounds checking (bnc#
1184673).
o CVE-2021-43389: An issue was discovered in the Linux kernel There was an
array-index-out-of-bounds flaw in the detach_capi_ctr function in drivers/
isdn/capi/kcapi.c (bnc#1191958).
o - ipv4: make exception cache less predictible (bsc#1191790,
CVE-2021-20322).
The following non-security bugs were fixed:
o Update config files: Add CONFIG_BPF_UNPRIV_DEFAULT_OFF is not set
o bpf: Add kconfig knob for disabling unpriv bpf by default (jsc#SLE-22918)
o bpf: Disallow unprivileged bpf by default (jsc#SLE-22918).
o bpf: properly enforce index mask to prevent out-of-bounds speculation (bsc#
1098425).
o btrfs: reloc: clear DEAD_RELOC_TREE bit for orphan roots to prevent runaway
balance (bsc#1188325).
o btrfs: reloc: fix reloc root leak and NULL pointer dereference (bsc#
1188325).
o btrfs: relocation: fix reloc_root lifespan and access (bsc#1188325).
o config: disable unprivileged BPF by default (jsc#SLE-22918) Backport of
mainline commit 8a03e56b253e ("bpf: Disallow unprivileged bpf by default")
only changes kconfig default, used e.g. for "make oldconfig" when the
config option is missing, but does not update our kernel configs used for
build. Update also these to make sure unprivileged BPF is really disabled
by default.
o kABI: protect struct bpf_map (kabi).
o s390/bpf: Fix 64-bit subtraction of the -0x80000000 constant (bsc#1190601).
o s390/bpf: Fix branch shortening during codegen pass (bsc#1190601).
o s390/bpf: Fix optimizing out zero-extensions (bsc#1190601).
o s390/bpf: Wrap JIT macro parameter usages in parentheses (bsc#1190601).
o s390: bpf: implement jitting of BPF_ALU | BPF_ARSH | BPF_* (bsc#1190601).
o scsi: sg: add sg_remove_request in sg_write (bsc#1171420 CVE2020-12770).
o sctp: check asoc peer.asconf_capable before processing asconf (bsc#
1190351).
o sctp: fully initialize v4 addr in some functions (bsc#1188563).
o sctp: simplify addr copy (bsc#1188563).

______________________________________________________________________________
An update that solves 6 vulnerabilities, contains one feature and has 21 fixes
is now available.
Description:
The SUSE Linux Enterprise 15 SP2 kernel was updated to receive various security
and bugfixes.
The following security bugs were fixed:
o Unprivileged BPF has been disabled by default to reduce attack surface as
too many security issues have happened in the past (jsc#SLE-22573)
You can reenable via systemctl setting /proc/sys/kernel/
unprivileged_bpf_disabled to 0. (kernel.unprivileged_bpf_disabled = 0)
o CVE-2021-0941: In bpf_skb_change_head of filter.c, there is a possible out
of bounds read due to a use after free. This could lead to local escalation
of privilege with System execution privileges needed. User interaction is
not needed for exploitation (bnc#1192045).
o CVE-2021-31916: An out-of-bounds (OOB) memory write flaw was found in
list_devices in drivers/md/dm-ioctl.c in the Multi-device driver module in
the Linux kernel A bound check failure allowed an attacker with special
user (CAP_SYS_ADMIN) privilege to gain access to out-of-bounds memory
leading to a system crash or a leak of internal kernel information. The
highest threat from this vulnerability is to system availability (bnc#
1192781).
o CVE-2021-20322: Make the ipv4 and ipv6 ICMP exception caches less
predictive to avoid information leaks about UDP ports in use. (bsc#1191790)
o CVE-2021-34981: Fixed file refcounting in cmtp when cmtp_attach_device
fails (bsc#1191961).
o CVE-2021-43389: There was an array-index-out-of-bounds flaw in the
detach_capi_ctr function in drivers/isdn/capi/kcapi.c (bnc#1191958).
o CVE-2021-37159: hso_free_net_device in drivers/net/usb/hso.c called
unregister_netdev without checking for the NETREG_REGISTERED state, leading
to a use-after-free and a double free (bnc#1188601).

______________________________________________________________________________
An update that solves 38 vulnerabilities and has 18 fixes is now available.
Description:
The SUSE Linux Enterprise 12 SP3 LTSS kernel was updated to receive various
security and bugfixes.
The following security bugs were fixed:
o Unprivileged BPF has been disabled by default to reduce attack surface as
too many security issues have happened in the past (jsc#SLE-22573)
You can reenable via systemctl setting /proc/sys/kernel/
unprivileged_bpf_disabled to 0. (kernel.unprivileged_bpf_disabled = 0)
o CVE-2021-31916: An out-of-bounds (OOB) memory write flaw was found in
list_devices in drivers/md/dm-ioctl.c in the Multi-device driver module in
the Linux kernel A bound check failure allowed an attacker with special
user (CAP_SYS_ADMIN) privilege to gain access to out-of-bounds memory
leading to a system crash or a leak of internal kernel information. The
highest threat from this vulnerability is to system availability (bnc#
1192781).
o CVE-2021-20322: Make the ipv4 and ipv6 ICMP exception caches less
predictive to avoid information leaks about UDP ports in use. (bsc#1191790)
o CVE-2021-34981: Fixed file refcounting in cmtp when cmtp_attach_device
fails (bsc#1191961).
o CVE-2020-12655: An issue was discovered in xfs_agf_verify in fs/xfs/libxfs/
xfs_alloc.c. Attackers may trigger a sync of excessive duration via an XFS
v5 image with crafted metadata, aka CID-d0c7feaf8767 (bnc#1171217).
o CVE-2021-43389: There was an array-index-out-of-bounds flaw in the
detach_capi_ctr function in drivers/isdn/capi/kcapi.c (bnc#1191958).
o CVE-2021-37159: hso_free_net_device in drivers/net/usb/hso.c called
unregister_netdev without checking for the NETREG_REGISTERED state, leading
to a use-after-free and a double free (bnc#1188601).
o CVE-2021-34556: An unprivileged BPF program can obtain sensitive
information from kernel memory via a Speculative Store Bypass side-channel
attack because the protection mechanism neglects the possibility of
uninitialized memory locations on the BPF stack (bnc#1188983).
o CVE-2021-35477: An unprivileged BPF program can obtain sensitive
information from kernel memory via a Speculative Store Bypass side-channel
attack because a certain preempting store operation did not necessarily
occur before a store operation that has an attacker-controlled value (bnc#
1188985).
o CVE-2017-17862: kernel/bpf/verifier.c in the Linux kernel ignores
unreachable code, even though it would still be processed by JIT compilers.
This behavior, also considered an improper branch-pruning logic issue,
could possibly be used by local users for denial of service (bnc#1073928).
o CVE-2017-17864: kernel/bpf/verifier.c in the Linux kernel mishandled
states_equal comparisons between the pointer data type and the
UNKNOWN_VALUE data type, which allowed local users to obtain potentially
sensitive address information, aka a "pointer leak (bnc#1073928).
o CVE-2021-20265: A flaw was found in the way memory resources were freed in
the unix_stream_recvmsg function in the Linux kernel when a signal was
pending. This flaw allowed an unprivileged local user to crash the system
by exhausting available memory. The highest threat from this vulnerability
is to system availability (bnc#1183089).
o CVE-2021-3772: Fixed sctp vtag check in sctp_sf_ootb (bsc#1190351).
o CVE-2021-3655: Missing size validations on inbound SCTP packets may have
allowed the kernel to read uninitialized memory (bnc#1188563).
o CVE-2018-13405: The inode_init_owner function in fs/inode.c in the Linux
kernel allowed local users to create files with an unintended group
ownership, in a scenario where a directory is SGID to a certain group and
is writable by a user who is not a member of that group. Here, the
non-member can trigger creation of a plain file whose group ownership is
that group. The intended behavior was that the non-member can trigger
creation of a directory (but not a plain file) whose group ownership is
that group. The non-member can escalate privileges by making the plain file
executable and SGID (bnc#1100416 bnc#1129735).
o CVE-2021-3760: Fixed a use-after-free vulnerability with the ndev->
rf_conn_info object (bsc#1190067).
o CVE-2021-42739: The firewire subsystem in the Linux kernel has a buffer
overflow related to drivers/media/firewire/firedtv-avc.c and drivers/media/
firewire/firedtv-ci.c, because avc_ca_pmt mishandled bounds checking (bnc#
1184673).
o CVE-2021-3542: Fixed heap buffer overflow in firedtv driver (bsc#1186063).
o CVE-2021-33033: The Linux kernel has a use-after-free in cipso_v4_genopt in
net/ipv4/cipso_ipv4.c because the CIPSO and CALIPSO refcounting for the DOI
definitions is mishandled, aka CID-ad5d07f4a9cd. This leads to writing an
arbitrary value (bnc#1186109 bnc#1186390 bnc#1188876).
o CVE-2020-14305: An out-of-bounds memory write flaw was found in how the
Linux kernel's Voice Over IP H.323 connection tracking functionality
handled connections on ipv6 port 1720. This flaw allowed an unauthenticated
remote user to crash the system, causing a denial of service. The highest
threat from this vulnerability is to confidentiality, integrity, as well as
system availability (bnc#1173346).
o CVE-2021-3715: Fixed a use-after-free in route4_change() in net/sched/
cls_route.c (bsc#1190349).
o CVE-2021-3896: Fixed a array-index-out-bounds in detach_capi_ctr in drivers
/isdn/capi/kcapi.c (bsc#1191958).
o CVE-2021-42008: The decode_data function in drivers/net/hamradio/6pack.c in
the Linux kernel has a slab out-of-bounds write. Input from a process that
has the CAP_NET_ADMIN capability can lead to root access (bnc#1191315).
o CVE-2020-3702: Specifically timed and handcrafted traffic can cause
internal errors in a WLAN device that lead to improper layer 2 Wi-Fi
encryption with a consequent possibility of information disclosure over the
air for a discrete set of traffic (bnc#1191193).
o CVE-2021-3752: Fixed a use after free vulnerability in the Linux kernel's
bluetooth module. (bsc#1190023)
o CVE-2021-40490: A race condition was discovered in
ext4_write_inline_data_end in fs/ext4/inline.c in the ext4 subsystem in the
Linux kernel (bnc#1190159 bnc#1192775)
o CVE-2021-3640: Fixed a Use-After-Free vulnerability in function
sco_sock_sendmsg() in the bluetooth stack (bsc#1188172).
o CVE-2021-38160: Data corruption or loss could be triggered by an untrusted
device that supplies a buf->len value exceeding the buffer size in drivers/
char/virtio_console.c (bsc#1190117)
o CVE-2021-3753: Fixed race out-of-bounds in virtual terminal handling (bsc#
1190025).
o CVE-2021-3732: Mounting overlayfs inside an unprivileged user namespace can
reveal files (bsc#1189706).
o CVE-2021-3653: A flaw was found in the KVM's AMD code for supporting SVM
nested virtualization. The flaw occurs when processing the VMCB (virtual
machine control block) provided by the L1 guest to spawn/handle a nested
guest (L2). Due to improper validation of the "int_ctl" field, this issue
could allow a malicious L1 to enable AVIC support (Advanced Virtual
Interrupt Controller) for the L2 guest. As a result, the L2 guest would be
allowed to read/write physical pages of the host, resulting in a crash of
the entire system, leak of sensitive data or potential guest-to-host
escape. This flaw affects Linux kernel versions prior to 5.14-rc7 (bnc#
1189399 bnc#1189420).
o CVE-2021-38198: arch/x86/kvm/mmu/paging_tmpl.h in the Linux kernel
incorrectly computes the access permissions of a shadow page, leading to a
missing guest protection page fault (bnc#1189262 bnc#1189278).
o CVE-2021-38204: drivers/usb/host/max3421-hcd.c in the Linux kernel allowed
physically proximate attackers to cause a denial of service (use-after-free
and panic) by removing a MAX-3421 USB device in certain situations (bnc#
1189291).
o CVE-2021-3679: A lack of CPU resource in the Linux kernel tracing module
functionality in versions prior to 5.14-rc3 was found in the way user uses
trace ring buffer in a specific way. Only privileged local users (with
CAP_SYS_ADMIN capability) could use this flaw to starve the resources
causing denial of service (bnc#1189057).
o CVE-2018-16882: A use-after-free issue was found in the way the Linux
kernel's KVM hypervisor processed posted interrupts when nested(=1)
virtualization is enabled. In nested_get_vmcs12_pages(), in case of an
error while processing posted interrupt address, it unmaps the
'pi_desc_page' without resetting 'pi_desc' descriptor address, which is
later used in pi_test_and_clear_on(). A guest user/process could use this
flaw to crash the host kernel resulting in DoS or potentially gain
privileged access to a system. Kernel versions and are vulnerable (bnc#
1119934).
o CVE-2020-0429: In l2tp_session_delete and related functions of l2tp_core.c,
there is possible memory corruption due to a use after free. This could
lead to local escalation of privilege with System execution privileges
needed. User interaction is not needed for exploitation (bnc#1176724).
o CVE-2020-4788: IBM Power9 (AIX 7.1, 7.2, and VIOS 3.1) processors could
allow a local user to obtain sensitive information from the data in the L1
cache under extenuating circumstances. IBM X-Force ID: 189296 (bnc#1177666
bnc#1181158).
o CVE-2021-3659: Fixed a NULL pointer dereference in llsec_key_alloc() in net
/mac802154/llsec.c (bsc#1188876).
o CVE-2021-37576: arch/powerpc/kvm/book3s_rtas.c in the Linux kernel on the
powerpc platform allowed KVM guest OS users to cause host OS memory
corruption via rtas_args.nargs, aka CID-f62f3c20647e (bnc#1188838).
The following non-security bugs were fixed:
o PCI: hv: Use expected affinity when unmasking IRQ (bsc#1185973).
o SUNRPC: improve error response to over-size gss credential (bsc#1190022).
o Update config files: Add CONFIG_BPF_UNPRIV_DEFAULT_OFF is not set

______________________________________________________________________________
An update that solves four vulnerabilities, contains one feature and has 21
fixes is now available.
Description:
The SUSE Linux Enterprise 15 SP3 kernel was updated to receive various security
and bugfixes.
The following security bugs were fixed:
o Unprivileged BPF has been disabled by default to reduce attack surface as
too many security issues have happened in the past (jsc#SLE-22573)
You can reenable via systemctl setting /proc/sys/kernel/
unprivileged_bpf_disabled to 0. (kernel.unprivileged_bpf_disabled = 0)
o CVE-2021-0941: In bpf_skb_change_head of filter.c, there is a possible out
of bounds read due to a use after free. This could lead to local escalation
of privilege with System execution privileges needed. User interaction is
not needed for exploitation (bnc#1192045 ).
o CVE-2021-31916: An out-of-bounds (OOB) memory write flaw was found in
list_devices in drivers/md/dm-ioctl.c in the Multi-device driver module in
the Linux kernel A bound check failure allowed an attacker with special
user (CAP_SYS_ADMIN) privilege to gain access to out-of-bounds memory
leading to a system crash or a leak of internal kernel information. The
highest threat from this vulnerability is to system availability (bnc#
1192781).
o CVE-2021-20322: Make the ipv4 and ipv6 ICMP exception caches less
predictive to avoid information leaks about UDP ports in use. (bsc#1191790)
o CVE-2021-34981: Fixed file refcounting in cmtp when cmtp_attach_device
fails (bsc#1191961).
The following non-security bugs were fixed:
o ABI: sysfs-kernel-slab: Document some stats (git-fixes).
o ALSA: hda: fix general protection fault in azx_runtime_idle (git-fixes).
o ALSA: hda: Free card instance properly at probe errors (git-fixes).
o ALSA: usb-audio: Add Audient iD14 to mixer map quirk table (git-fixes).

o ALSA: usb-audio: Add Schiit Hel device to mixer map quirk table
(git-fixes).
o ALSA: usb-audio: Fix dB level of Bose Revolve+ SoundLink (bsc#1192375).
o ALSA: usb-audio: Use int for dB map values (bsc#1192375).
o ARM: socfpga: Fix crash with CONFIG_FORTIRY_SOURCE (bsc#1192473).
o auxdisplay: ht16k33: Connect backlight to fbdev (git-fixes).
o auxdisplay: ht16k33: Fix frame buffer device blanking (git-fixes).
o auxdisplay: img-ascii-lcd: Fix lock-up when displaying empty string
(git-fixes).
o bpf: Add kconfig knob for disabling unpriv bpf by default (jsc#SLE-22573)
o bpf: Add kconfig knob for disabling unpriv bpf by default (jsc#SLE-22574)
o bpf: Disallow unprivileged bpf by default (jsc#SLE-22573).
o bpf: Disallow unprivileged bpf by default (jsc#SLE-22574).
o bpf: Fix BPF_JIT kconfig symbol dependency (git-fixes jsc#SLE-22574).
o bpf: Fix potential race in tail call compatibility check (git-fixes).
o bpf, kconfig: Add consolidated menu entry for bpf with core options (jsc#
SLE-22574).

o cgroup/cpuset: Change references of cpuset_mutex to cpuset_rwsem
(git-fixes).
o config: disable unprivileged BPF by default (jsc#SLE-22573) Backport of
mainline commit 8a03e56b253e ("bpf: Disallow unprivileged bpf by default")
only changes kconfig default, used e.g. for "make oldconfig" when the
config option is missing, but does not update our kernel configs used for
build. Update also these to make sure unprivileged BPF is really disabled
by default.
