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

Security Fix(es):

  • kernel: use after free in eventpoll.c may lead to escalation of privilege (CVE-2020-0466)

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

  • kernel: xfs: raw block device data leak in XFS_IOC_ALLOCSP IOCTL (CVE-2021-4155)

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

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.
