The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fix: * kernel: improper initialization of the "flags" member of the new pipe_buffer * kernel: Use After Free in unix_gc which could result in a local privilege escalation * kernel: local privilege escalation by exploiting the fsconfig syscall parameter leads to container breakout * kernel: possible privileges escalation due to missing TLB flush * kernel: remote stack overflow via kernel panic on systems using TIPC may lead to DoS * kernel: cgroups v1 release_agent feature may allow privilege escalation * kernel: failing usercopy allows for use-after-free exploitation For more details about the security issue, including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page listed in the References section. Bug Fix: * kernel symbol "__rt_mutex_init" is exported GPL-only in kernel 4.18.0-348.2.1.rt7.132.el8_5 * kernel-rt: update RT source tree to the Rocky Linux-8.5.z3 source tree
