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: stack overflow in do_proc_dointvec and proc_skip_spaces (CVE-2022-4378)
  • ALSA: pcm: Move rwsem lock inside snd_ctl_elem_read to prevent UAF (CVE-2023-0266)
  • kernel: FUSE filesystem low-privileged user privileges escalation (CVE-2023-0386)
  • kernel: net: CPU soft lockup in TC mirred egress-to-ingress action (CVE-2022-4269)

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):

  • Lazy irq_work does not raise softirq on PREEMPT_RT [almalinux-8] (BZ#2172163)
  • The latest AlmaLinux 8.7.z3 kernel changes need to be merged into the RT source tree to keep source parity between the two kernels. (BZ#2172278)
