Synopsis

Important: kernel security update

Description

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es):

* kernel: md/bitmap: fix GPF in write_page caused by resize race (CVE-2026-43163)

* kernel: rtmutex: Use waiter::task instead of current in remove_waiter() (CVE-2026-43499)

* kernel: futex/requeue: Prevent NULL pointer dereference in remove_waiter() on self-deadlock (CVE-2026-53166)

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.
