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: 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-2022-1966)
* kernel: buffer overflow in IPsec ESP transformation code (CVE-2022-27666)
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 latest AlmaLinux-9.0.z1 Batch (BZ#2089492)
