Summary
Important: kernel-rt security, bug fix, and enhancement 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: Linux kernel: Use-after-free in bonding driver leads to denial of service (CVE-2026-31419)
  • kernel: drm/amd/display: Do not skip unrelated mode changes in DSC validation (CVE-2026-31488)
  • kernel: net: mana: fix use-after-free in add_adev() error path (CVE-2026-43056)
  • kernel: ALSA: usb-audio: Add sanity check for OOB writes at silencing (CVE-2026-43279)
  • kernel: net/sched: act_pedit: extend the writable skb range per key (CVE-2026-46331)
  • kernel: ALSA: aloop: Fix peer runtime UAF during format-change stop (CVE-2026-46090)
  • kernel: RDMA/mana: Validate rxhashkey_len (CVE-2026-46145)
  • kernel: nvmet-tcp: fix race between ICReq handling and queue teardown (CVE-2026-46135)

Bug Fix(es) and Enhancement(s):

  • AlmaLinux8 RT kernel panic in replenishdlentity() caused by stale DEADLINE PI state during rt_mutex de-boosting (JIRA:AlmaLinux-178520)
