That results in several\nproblems:\n\n 1) the rbtree dequeue happens without waiter::task::pi_lock being held\n\n 2) the waiter task's pi_blocked_on state is not cleared, which leaves a\n dangling pointer primed for UAF around.\n\n 3) rt_mutex_adjust_prio_chain() operates on the wrong top priority waiter\n task\n\nUse waiter::task instead of current in all related operations in\nremove_waiter()

pi_lock give a use-after-free over reclaimed stack memory, which can be leveraged to read controlled kernel memory contents.\nI:H - The UAF and unsynchronized rbtree manipulation provide a write
