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: vsock/vmci: Clear the vmci transport packet properly when initializing it (CVE-2025-38403)
  • kernel: net: use dst_dev_rcu() in sk_setup_caps() (CVE-2025-40170)
  • kernel: ipv6: use RCU in ip6_xmit() (CVE-2025-40135)
  • kernel: ipv6: use RCU in ip6_output() (CVE-2025-40158)
  • kernel: Linux kernel ALSA USB audio driver: Buffer overflow leading to information disclosure and denial of service (CVE-2025-40269)
  • kernel: ext4: fix use-after-free in ext4_orphan_cleanup (CVE-2022-50673)
  • kernel: NFSv4/pNFS: Clear NFS_INO_LAYOUTCOMMIT in pnfs_mark_layout_stateid_invalid (CVE-2025-68349)
  • kernel: nvme-tcp: fix NULL pointer dereferences in nvmet_tcp_build_pdu_iovec (CVE-2026-22998)
