Title:RHSA-2022:0849: kpatch-patch security update (Important)
Description:This is a kernel live patch module which is automatically loaded by the RPM post-install script to modify the code of a running kernel.

Security Fix(es):

  • kernel: Use After Free in unix_gc() which could result in a local privilege escalation (CVE-2021-0920)

  • kernel: local privilege escalation by exploiting the fsconfig syscall parameter leads to container breakout (CVE-2021-4154)

  • kernel: possible privileges escalation due to missing TLB flush (CVE-2022-0330)

  • kernel: remote stack overflow via kernel panic on systems using TIPC may lead to DoS (CVE-2022-0435)

  • kernel: cgroups v1 release_agent feature may allow privilege escalation (CVE-2022-0492)

  • kernel: failing usercopy allows for use-after-free exploitation (CVE-2022-22942)
