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...
