    Summary: Important: kernel-rt security and bug fix update

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