…ter() on self-deadlock"" cve-bf CVE-2026-53166 commit-author Sebastian Andrzej Siewior <bigeasy@linutronix.de> commit 39def6d The commit cited below should not have been merged. It attemted to fix an existing problem ansd thereby introduced new problems by keeping the pi_state in state Q_REQUEUE_PI_IN_PROGRESS and leaking it. Based on the commit description the intention was to handle the case when task_blocks_on_rt_mutex() returns -EDEADLK and the following remove_waiter() dereferences the NULL pointer in waiter->task. That is already handled by Davidlohr in commit 40a25d5 ("locking/rtmutex: Skip remove_waiter() when waiter is not enqueued") and requires no further acting. Revert the commit breaking the "waiter == owner" case again. Fixes: 74e1442 ("futex/requeue: Prevent NULL pointer dereference in remove_waiter() on self-deadlock") Reported-by: Michael Bommarito <michael.bommarito@gmail.com> Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: Thomas Gleixner <tglx@kernel.org> Cc: stable@vger.kernel.org Link: https://patch.msgid.link/20260701131150.0Ijhq4Dw@linutronix.de Closes: https://lore.kernel.org/all/20260629020049.2082397-1-michael.bommarito@gmail.com (cherry picked from commit 39def6d) Signed-off-by: Brett Mastbergen <bmastbergen@ciq.com>
