kernel: posix-cpu-timers: fix race between handle_posix_cpu_timers() and posix_cpu_timer_del()

A race condition was found in the Linux kernel’s POSIX CPU timer handling, where handleposixcputimers may run concurrently with posixcputimerdel on an exiting task which could result in use-after-free scenarios. An attacker with local user access could use this flaw to crash or escalate their...
