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: 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)
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):
- AlmaLinux8-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 AlmaLinux 8.7.z2 kernel changes need to be merged into the RT source tree to keep source parity between the two kernels. (BZ#2159806)
