[ALSA-2026:55765] Important: kernel-rt security, bug fix, and enhancement update
Type:
security
Severity:
important
Release date:
2026-08-18
Description:
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: mm/slub: avoid accessing metadata when pointer is invalid in object_err() (CVE-2025-39902) * kernel: drm/amdkfd: Fix out-of-bounds write in kfd_event_page_set() (CVE-2026-43206) * kernel: crypto: ccp - copy IV using skcipher ivsize (CVE-2026-53016) * kernel: drm/amd/display: Clamp VBIOS HDMI retimer register count to array size (CVE-2026-53136) * kernel: drm/amd/display: Use krealloc_array() in dal_vector_reserve() (CVE-2026-53329) * kernel: drm/amdgpu: zero-initialize GART table on allocation (CVE-2026-53374) * kernel: drm/i915: Fix potential UAF in TTM object purge (CVE-2026-63884) * kernel: drm/amdgpu: fix amdgpu_hmm_range_get_pages (CVE-2026-63879) * kernel: drm/amd/display: Validate payload length and link_index in dc_process_dmub_aux_transfer_async (CVE-2026-64219) * kernel: can:bcm: arbitrary kernel code execution leading to escalate privileges (CVE-2026-17523) Bug Fix(es) and Enhancement(s): * Backport "sched/deadline: Fix bandwidth reclaim equation in GRUB" to AlmaLinux 8.10 (JIRA:AlmaLinux-189997) * vhost: reset the vring metadata cache on vring reconfiguration [almalinux-8.10.z] (JIRA:AlmaLinux-224556) 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.
