Summary
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: improper initialization of the "flags" member of the new pipe_buffer (CVE-2022-0847)
* kernel: Use After Free in unix_gc() which could result in a local privilege escalation (CVE-2021-0920)
* kernel: local privilege escalation by exploiting the fsconfig syscall parameter leads to container breakout (CVE-2021-4154)
* kernel: possible privileges escalation due to missing TLB flush (CVE-2022-0330)
* kernel: remote stack overflow via kernel panic on systems using TIPC may lead to DoS (CVE-2022-0435)
* kernel: cgroups v1 release_agent feature may allow privilege escalation (CVE-2022-0492)
* kernel: failing usercopy allows for use-after-free exploitation (CVE-2022-22942)
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 symbol '__rt_mutex_init' is exported GPL-only in kernel 4.18.0-348.2.1.rt7.132.el8_5 (BZ#2038423)
* kernel-rt: update RT source tree to the Rocky Linux-8.5.z3 source tree (BZ#2045589)
