ALSA-2023:3350 Not scored

Important: kernel-rt security and bug fix update

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: netfilter: use-after-free in nf_tables when processing batch requests can lead to privilege escalation (CVE-2023-32233) 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): * smpboot: Scheduler frequency invariance went wobbly, disabling! (BZ#2188316) * Crash: kernel BUG at kernel/locking/rtmutex.c:1338! (BZ#2188722) * kernel-rt: update RT source tree to the AlmaLinux-8.8.z0 source tree. (BZ#2196667)
