Summary
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: mm/mremap.c use-after-free vulnerability (CVE-2022-41222)
* kernel: nfsd buffer overflow by RPC message over TCP with garbage data (CVE-2022-43945)
* kernel: an out-of-bounds vulnerability in i2c-ismt driver (CVE-2022-2873)

Bug Fix(es):
* Rocky Linux8-RT: Backport use of a dedicate thread for timer wakeups (BZ#2127204)
* SNO Crashed twice - kernel BUG at lib/list_debug.c:28 (BZ#2132062)
* Cannot trigger kernel dump using NMI on SNO node running PAO and RT kernel [RT-8] (BZ#2139851)
* scheduling while atomic in fpu_clone() -> fpu_inherit_perms() (BZ#2154469)
* The latest Rocky Linux 8.7.z2 kernel changes need to be merged into the RT source tree to keep source parity between the two kernels. (BZ#2159806)
