Important: kernel security update

The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * kernel: mptcp: fix slab-use-after-free in __inet_lookup_established (CVE-2026-31669) * kernel: xen/privcmd: fix double free via VMA splitting (CVE-2026-31787) * kernel: Buffer overflow in drivers/xen/sys-hypervisor.c (CVE-2026-31786) * kernel: wifi: brcmfmac: validate bsscfg indices in IF events (CVE-2026-43110) * kernel: netfilter: flowtable: strictly check for maximum number of actions (CVE-2026-43329) * kernel: Bluetooth: hci_event: fix potential UAF in SSP passkey handlers (CVE-2026-46056) * kernel: wifi: mac80211: drop stray 'static' from fast-RX rx_result (CVE-2026-46152) * kernel: wifi: mac80211: remove station if connection prep fails (CVE-2026-46125) 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.
