kernel: rtmutex: Use waiter::task instead of current in remove_waiter()

A flaw was found in the Linux kernel. When the kernel's real-time mutex rtmutex component performs a specific operation called 'proxy-lock rollback' during futex requeue, it incorrectly handles task pointers. This can lead to a 'Use-After-Free' UAF vulnerability, where the system attempts to use...

kernel: futex: Prevent lockup in requeue-PI during signal/ timeout wakeup

A flaw was found in the Linux kernel's futex Fast Userspace Mutexes subsystem. A race condition between two concurrent futex operations can lead to a system live lock. This occurs when a task attempting to exit early due to a signal or timeout becomes deadlocked while another task continuously...
