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: nvme: avoid double free special payload (CVE-2024-41073)
  • kernel: net: qlogic/qede: fix potential out-of-bounds read in qede_tpa_cont() and qede_tpa_end() (CVE-2025-40252)
  • kernel: crypto: asymmetric_keys - prevent overflow in asymmetric_key_generate_id (CVE-2025-68724)
  • kernel: nfsd: fix heap overflow in NFSv4.0 LOCK replay cache (CVE-2026-31402)
  • kernel: Linux kernel KVM: Privilege escalation or denial of service due to improper shadow page table entry handling (CVE-2026-23401)
  • kernel: crypto: algif_aead - Revert to operating out-of-place (CVE-2026-31431)
