The kernel packages contain the Linux kernel, the core of any Linux operating system.

The following packages have been upgraded to a later upstream version: kernel (4.18.0). (BZ#2036888)

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)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
