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: nfsd: don't ignore the return code of svc_proc_register() (CVE-2025-22026)
  • kernel: net_sched: hfsc: Fix a UAF vulnerability in class handling (CVE-2025-37797)
  • kernel: firmware: arm_scpi: Ensure scpi_info is not assigned if the probe fails (CVE-2022-50087)
  • kernel: sctp: linearize cloned gso packets in sctp_rcv (CVE-2025-38718)

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.
