(RHSA-2022:5633) Important: kernel-rt security and bug fix update

Description

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: Small table perturb size in the TCP source port generation algorithm can lead to information leak (CVE-2022-1012) * 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-2022-32250) * kernel: cgroup: Use open-time creds and namespace for migration perm checks (CVE-2021-4197) * kernel: Race condition in races in sk_peer_pid and sk_peer_cred accesses (CVE-2021-4203) * kernel: the copy-on-write implementation can grant unintended write access because of a race condition in a THP mapcount check (CVE-2020-29368) 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.z10 source tree (BZ#2087922)
