Summary
Moderate: 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: cifs: fix double free race when mount fails in cifs_get_root() (CVE-2022-48919)
  • kernel: security/keys: fix slab-out-of-bounds in key_task_permission (CVE-2024-50301)
  • kernel: idpf: fix idpf_vc_core_init error path (CVE-2024-53064)
  • kernel: ndisc: use RCU protection in ndisc_alloc_skb() (CVE-2025-21764)

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.
