Synopsis

Important: kernel security update



Description

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

Security Fix(es):

* kernel: fs/notify: call exportfs_encode_fid with s_umount (CVE-2025-40237)

* kernel: scsi: core: Wake up the error handler when final completions race against each other (CVE-2026-23110)

* kernel: rtnetlink: add missing netlink_ns_capable() check for peer netns (CVE-2026-31692)

* kernel: net: ipv6: fix NOREF dst use in seg6 and rpl lwtunnels (CVE-2026-46099)

* kernel: futex: Drop CLONE_THREAD requirement for private default hash alloc (CVE-2026-52973)

* kernel: dm log: fix out-of-bounds write due to region_count overflow (CVE-2026-53059)
