CentOS Errata and Security Advisory CESA-2022:5232

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

Security Fix(es):

  • kernel: race condition in perf_event_open leads to privilege escalation (CVE-2022-1729)

  • kernel: a use-after-free write in the netfilter subsystem can lead to privilege escalation to root (CVE-2022-1966)

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.

Bug Fix(es):

  • XFS inode cluster corruption (BZ#2050464)

  • sock: sock_dequeue_err_skb() needs hard irq safety (BZ#2070408)

  • libceph: fix potential use-after-free on linger ping and resends (BZ#2088025)
