Important: kernel security, bug fix, and enhancement update
The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * kernel: fsnotify: Fix ordering of iput() and watched_objects decrement (CVE-2024-53143) * kernel: shmem: fix recovery on rename failures (CVE-2025-71072) * kernel: futex: Fix UaF between futex_key_to_node_opt() and vma_replace_policy() (CVE-2026-23415) * kernel: drm/amd/display: Do not skip unrelated mode changes in DSC validation (CVE-2026-31488) * kernel: ipc: limit next_id allocation to the valid ID range (CVE-2026-52923) * kernel: mm/slab: do not limit zeroing to orig_size when only red zoning is enabled (CVE-2026-64368) * kernel: net: openvswitch: reject oversized nested action attrs (CVE-2026-64531) Bug Fix(es) and Enhancement(s): * Kernel oops after increasing max number of mac addresses of a mlx5 VF [almalinux-10.2.z] (JIRA:AlmaLinux-213035) * AlmaLinux10.0 - s390/pkey: Check length in PKEY_VERIFYPROTK ioctl [almalinux-10.2.z] (JIRA:AlmaLinux-222503) * AlmaLinux10.0 - s390/pkey: Check length in pkey_pckmo handler implementation [almalinux-10.2.z] (JIRA:AlmaLinux-222505) 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.
