MR: https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-10/-/merge_requests/2902 JIRA: https://redhat.atlassian.net/browse/RHEL-193249 CVE: CVE-2026-53166 MR: https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-10/-/merge_requests/2902 The CVE references commit 74e144274af3 ("futex/requeue: Prevent NULL pointer dereference in remove_waiter() on self-deadlock"), but it was reverted upstream and commit 40a25d59e85b ("locking/rtmutex: Skip remove_waiter() when waiter is not enqueued") is regarded as the proper fix for the same problem. So all of them are included in this MR for completeness.
