[RHSA-2022:5565] kernel-rt security and bug fix update

Severity Important
Affected Packages 12
CVEs 1
Info Packages References Vulnerabilities

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

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):

  • The latest RHEL 8.6.z1 kernel changes need to be merged into the RT source tree to keep source parity between the two kernels. (BZ#2098244)
