Summary
Moderate: kernel security update
Details

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

  • kernel: Linux kernel (net/mlx5): Use-after-free in ECVF vports unload leads to denial of service (CVE-2025-38109)
  • kernel: Linux kernel: Local denial of service and memory leak in DAMON sysfs via setup failure (CVE-2026-23144)
  • kernel: Linux kernel: Use-after-free in bonding module can cause system crash or arbitrary code execution (CVE-2026-23171)
  • kernel: scsi: target: iscsi: Fix use-after-free in iscsit_dec_session_usage_count() (CVE-2026-23193)
  • kernel: macvlan: fix error recovery in macvlan_common_newlink() (CVE-2026-23209)
  • kernel: net/sched: cls_u32: use skb_header_pointer_careful() (CVE-2026-23204)
  • kernel: ALSA: aloop: Fix racy access at PCM trigger (CVE-2026-23191)
