SUSE-SU-2022:2268-1

This update for the Linux Kernel 5.14.21-150400_22 fixes several issues.

The following security issues were fixed:

• CVE-2022-32250: Fixed an use-after-free bug in the netfilter subsystem. This flaw allowed a local attacker with user access to cause a privilege escalation issue. (bnc#1200015)
• CVE-2022-1972: Fixed a buffer overflow in nftable that could lead to privilege escalation. (bsc#1200019)
• CVE-2022-30594: Fixed restriction bypass on setting the PTSUSPENDSECCOMP flag (bnc#1199505).
• CVE-2022-1280: Fixed a use-after-free vulnerability in drmleaseheld in drivers/gpu/drm/drm_lease.c (bnc#1197914).
• CVE-2022-1280: Fixed a use-after-free vulnerability in drmleaseheld in drivers/gpu/drm/drm_lease.c (bnc#1197914).
• CVE-2022-1016: Fixed a vulnerability in the nf_tables component of the netfilter subsystem. This vulnerability gives an attacker a powerful primitive that can be used to both read from and write to relative stack data, which can lead to arbitrary code execution. (bsc#1197227)
• CVE-2021-39698: Fixed a possible memory corruption due to a use after free in aiopollcomplete_work. This could lead to local escalation of privilege with no additional execution privileges needed. (bsc#1196956)
