QID 240128: Red Hat Update for kernel security (RHSA-2022:0825)

the kernel packages contain the linux kernel, the core of any linux operating system.

Security Fix(es):
  • kernel: improper initialization of the "flags" member of the new pipe_buffer (cve-2022-0847)
  • 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: missing check in ioctl allows kernel memory read/write (cve-2022-0516)
  • kernel: failing usercopy allows for use-after-free exploitation (cve-2022-22942)

  • Red Hat virtualization host 4 for rhel 8 x86_64
  • Red Hat enterprise linux for x86_64 8 x86_64
