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 eventpoll.c may lead to escalation of privilege (CVE-2020-0466)

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

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

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.
