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: buffer overflow in IPsec ESP transformation code (CVE-2022-27666) * kernel: out-of-bounds read in fbcon_get_font function (CVE-2020-28915) 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): * kernel-rt: update RT source tree to the latest AlmaLinux-8.6.z0 Batch (BZ#2081704)
