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: memory corruption in AX88179_178A based USB ethernet device. (CVE-2022-2964)
* kernel: i915: Incorrect GPU TLB flush can lead to random memory access (CVE-2022-4139)
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):
* The latest AlmaLinux 8.7.z1 kernel changes need to be merged into the RT source tree to keep source parity between the two kernels. (BZ#2137411)
* [DELL EMC 8.6-RT BUG] System is not booting into RT Kernel with perc12. (BZ#2139867)
