Important: kernel security update
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)
