The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements.

Security Fix(es):

  • kernel: fget: check that the fd still exists after getting a ref to it (CVE-2021-4083)

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

  • kernel: heap out of bounds write in nf_dup_netdev.c (CVE-2022-25636)

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):

  • kernel-rt: update RT source tree to the RHEL-8.4.z8 source tree (BZ#2059334)
