Important: kernel-rt security update

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: rtnetlink: add missing netlink_ns_capable() check for peer netns (CVE-2026-31692) * kernel: netfilter: ctnetlink: ensure safe access to master conntrack (CVE-2026-43116) * kernel: fanotify: fix false positive on permission events (CVE-2026-46150) * kernel: net: sched: UAF via missing handler for TC_ACT_CONSUMED in tcf_qevent_handle () * kernel: net/sched: cls_api: Handle TC_ACT_CONSUMED in tcf_qevent_handle (CVE-2026-64530) 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.
