An update that solves 23 vulnerabilities and has four 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 CVE-2018-25020: Fixed an overflow in the BPF subsystem due to a mishandling
of a long jump over an instruction sequence where inner instructions
require substantial expansions into multiple BPF instructions. This affects
kernel/bpf/core.c and net/core/filter.c (bnc#1193575).
o CVE-2019-0136: Fixed insufficient access control in the Intel(R) PROSet/
Wireless WiFi Software driver that may have allowed an unauthenticated user
to potentially enable denial of service via adjacent access (bnc#1193157).
o CVE-2020-35519: Fixed out-of-bounds memory access in x25_bind in net/x25/
af_x25.c. A bounds check failure allowed a local attacker with a user
account on the system to gain access to out-of-bounds memory, leading to a
system crash or a leak of internal kernel information (bnc#1183696).
o CVE-2021-0935: Fixed possible out of bounds write in ip6_xmit of
ip6_output.c 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#1192032).
o CVE-2021-28711: Fixed issue with xen/blkfront to harden blkfront against
event channel storms (XSA-391) (bsc#1193440).
o CVE-2021-28712: Fixed issue with xen/netfront to harden netfront against
event channel storms (XSA-391) (bsc#1193440).
o CVE-2021-28713: Fixed issue with xen/console to harden hvc_xen against
event channel storms (XSA-391) (bsc#1193440).
o CVE-2021-28715: Fixed issue with xen/netback to do not queue unlimited
number of packages (XSA-392) (bsc#1193442).
o CVE-2021-33098: Fixed improper input validation in the Intel(R) Ethernet
ixgbe driver that may have allowed an authenticated user to potentially
cause denial of service via local access (bnc#1192877).
o CVE-2021-3564: Fixed double-free memory corruption in the Linux kernel HCI
device initialization subsystem that could have been used by attaching
malicious HCI TTY Bluetooth devices. A local user could use this flaw to
crash the system (bnc#1186207).
o CVE-2021-39648: Fixed possible disclosure of kernel heap memory due to a
race condition in gadget_dev_desc_UDC_show of configfs.c. This could lead
to local information disclosure with System execution privileges needed.
User interaction is not needed for exploitation (bnc#1193861).
o CVE-2021-39657: Fixed out of bounds read due to a missing bounds check in
ufshcd_eh_device_reset_handler of ufshcd.c. This could lead to local
information disclosure with System execution privileges needed (bnc#
1193864).
o CVE-2021-4002: Fixed incorrect TLBs flush in hugetlbfs after
huge_pmd_unshare (bsc#1192946).
o CVE-2021-4083: Fixed a read-after-free memory flaw inside the garbage
collection for Unix domain socket file handlers when users call close() and
fget() simultaneouslyand can potentially trigger a race condition (bnc#
1193727).
o CVE-2021-4149: Fixed btrfs unlock newly allocated extent buffer after error
(bsc#1194001).
o CVE-2021-4155: Fixed XFS map issue when unwritten blocks in XFS_IOC_
{ALLOC,FREE}SP just like fallocate (bsc#1194272).
o CVE-2021-4197: Use cgroup open-time credentials for process migraton perm
checks (bsc#1194302).
o CVE-2021-4202: Fixed NFC race condition by adding NCI_UNREG flag (bsc#
1194529).
o CVE-2021-43976: Fixed insufficient access control in drivers/net/wireless/
marvell/mwifiex/usb.c that allowed an attacker who connect a crafted USB
device to cause denial of service (bnc#1192847).
o CVE-2021-45095: Fixed refcount leak in pep_sock_accept in net/phonet/pep.c
(bnc#1193867).
o CVE-2021-45485: Fixed information leak in the IPv6 implementation in net/
ipv6/output_core.c (bnc#1194094).
o CVE-2021-45486: Fixed information leak inside the IPv4 implementation
caused by very small hash table (bnc#1194087).
o CVE-2022-0330: Fixed flush TLBs before releasing backing store (bsc#
1194880).
The following non-security bugs were fixed:
o fget: clarify and improve __fget_files() implementation (bsc#1193727).
o hv_netvsc: Fix the queue_mapping in netvsc_vf_xmit() (bsc#1193507).
o hv_netvsc: Set needed_headroom according to VF (bsc#1193507).
o kprobes: Limit max data_size of the kretprobe instances (bsc#1193669).
o memstick: rtsx_usb_ms: fix UAF
o moxart: fix potential use-after-free on remove path (bsc1194516).
o net/x25: fix a race in x25_bind() (networking-stable-19_03_15).
o net: mana: Add RX fencing (bsc#1193507).
o net: mana: Allow setting the number of queues while the NIC is down (bsc#
1193507).
o net: mana: Fix spelling mistake "calledd" -> "called" (bsc#1193507).
o net: mana: Fix the netdev_err()'s vPort argument in mana_init_port() (bsc#
1193507).
o net: mana: Improve the HWC error handling (bsc#1193507).
o net: mana: Support hibernation and kexec (bsc#1193507).
o net: mana: Use kcalloc() instead of kzalloc() (bsc#1193507).
o recordmcount.pl: fix typo in s390 mcount regex (bsc#1192267).
o recordmcount.pl: look for jgnop instruction as well as bcrl on s390 (bsc#
1192267).
o ring-buffer: Protect ring_buffer_reset() from reentrancy (bsc#1179960).
o tty: hvc: replace BUG_ON() with negative return value (git-fixes).

(git-fixes).

o xen/netfront: disentangle tx_skb_freelist (git-fixes).
o xen/netfront: do not bug in case of too many frags (bnc#1012382).
o xen/netfront: do not cache skb_shinfo() (bnc#1012382).
o xen/netfront: do not read data from request on the ring page (git-fixes).
o xen/netfront: do not trust the backend response data blindly (git-fixes).
o xen/netfront: read response from backend only once (git-fixes).
