Affected Products:
SUSE Linux Enterprise Module for Public Cloud 15-SP2
______________________________________________________________________________
An update that solves 6 vulnerabilities and has 23 fixes is now available.
Description:
The SUSE Linux Enterprise 15 SP2 Azure 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).

Affected Products:
SUSE Linux Enterprise Module for Public Cloud 15-SP3
______________________________________________________________________________
An update that solves 6 vulnerabilities, contains one feature and has 35 fixes
is now available.
Description:
The SUSE Linux Enterprise 15 SP3 kernel for Azure 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).
