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: smb: client: Fix use-after-free in cifs_fill_dirent (CVE-2025-38051)
  • kernel: smb: client: let recv_done verify data_offset, data_length and remaining_data_length (CVE-2025-39933)
  • kernel: drm/i915: mark requests for GuC virtual engines to avoid use-after-free (CVE-2023-53552)
  • kernel: drm/sched: Fix potential double free in drm_sched_job_add_resv_dependencies (CVE-2025-40096)
  • kernel: net: atlantic: fix fragment overflow handling in RX path (CVE-2025-68301)

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.
