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: a use-after-free write in the netfilter subsystem can lead to privilege escalation to root (CVE-2022-32250)

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 Rocky Linux 8.6.z2 kernel changes need to be merged into the RT source tree to keep source parity between the two kernels. (BZ#2107215)
