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: TIPC message reassembly use-after-free remote code execution vulnerability (CVE-2024-36886)
kernel: fs: sysfs: Fix reference leak in sysfs_break_active_protection() (CVE-2024-26993)
kernel: wifi: mac80211: Avoid address calculations via out of bounds array indexing (CVE-2024-41071)
