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: KVM: cmpxchg_gpte can write to pfns outside the userspace region (CVE-2022-1158)
kernel: openvswitch: integer underflow leads to out-of-bounds write in reserve_sfa_size() (CVE-2022-2639)
kernel: watch queue race condition can lead to privilege escalation (CVE-2022-2959)
kernel: nfsd buffer overflow by RPC message over TCP with garbage data (CVE-2022-43945)
