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: Linux kernel: Memory leak in networking due to incorrect GRO packet handling (CVE-2026-22979) * kernel: rtmutex: Use waiter::task instead of current in remove_waiter() (CVE-2026-43499) * kernel: net: bridge: use a stable FDB dst snapshot in RCU readers (CVE-2026-46086) * kernel: crypto: ccp - copy IV using skcipher ivsize (CVE-2026-53016) * kernel: futex/requeue: Prevent NULL pointer dereference in remove_waiter() on self-deadlock (CVE-2026-53166) Bug Fix(es) and Enhancement(s): * Kernel panic very early during boot while reading a tracefs file (available_filter_functions) due to invalid module name pointer [9.8.z] (JIRA:AlmaLinux-183236) 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.
