Summary
Important: kernel-rt security 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: net/sched: Always pass notifications when child class becomes empty (CVE-2025-38350)
  • kernel: idpf: convert control queue mutex to a spinlock (CVE-2025-38392)
  • kernel: drm/gem: Acquire references on GEM handles for framebuffers (CVE-2025-38449)

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.
