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: padata: fix UAF in padata_reorder (CVE-2025-21727)
  • kernel: ipv6: mcast: extend RCU protection in igmp6_send() (CVE-2025-21759)
  • kernel: can: peak_usb: fix use after free bugs (CVE-2021-47670)
  • kernel: mm/hugetlb: fix huge_pmd_unshare() vs GUP-fast race (CVE-2025-38085)
  • kernel: wifi: rtw88: fix the 'para' buffer size to avoid reading out of bounds (CVE-2025-38159)
