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: drm/amd/display: Do not skip unrelated mode changes in DSC validation (CVE-2026-31488) * kernel: ipv6: icmp: clear skb2->cb[] in ip6_err_gen_icmpv6_unreach() (CVE-2026-43038) * kernel: netfilter: flowtable: strictly check for maximum number of actions (CVE-2026-43329) * kernel: ALSA: aloop: Fix peer runtime UAF during format-change stop (CVE-2026-46090) * kernel: selinux: fix overlayfs mmap() and mprotect() access checks (CVE-2026-46054) * kernel: RDMA/iwcm: Fix workqueue list corruption by removing work_list (CVE-2026-45898) * kernel: RDMA/vmw_pvrdma: Fix double free on pvrdma_alloc_ucontext() error path (CVE-2026-46189) * kernel: RDMA/mlx5: Fix error path fall-through in mlx5_ib_dev_res_srq_init() (CVE-2026-46176) * kernel: KVM: arm64: vgic-its: Drop the translation cache reference only for the erased entry (CVE-2026-46316) Bug Fix(es) and Enhancement(s): * [AlmaLinux-9.8.z]: Update the mlx5 drivers to v6.19 (JIRA:AlmaLinux-169057) * iavf: during POD churn vlan filters may not be added for a vlan interface, spoofchk drops subsequent packets [almalinux-9.8.z] (JIRA:AlmaLinux-172993) * nf_conntrack_sctp: vtag corruption with late INIT in ESTABLISHED state across conntrack zones [almalinux-9.8.z] (JIRA:AlmaLinux-178273) * sched/fair: Skip sched_balance_running cmpxchg when balance is not due [almalinux-9.8.z] (JIRA:AlmaLinux-182776) * [REGRESSION] ISST-Spyre: Jenkins workload causes soft lock warning to appear on screen.
