CVE-2022-50095

The CVE-2022-50095 issue affects the Linux kernel posix-cpu-timers: when a non-leader thread execs, the timer’s task reference may point to the old PID, so exit_itimers cannot disarm armed timers. This could leave timers in the timerqueue_list and, during processing, cause a use-after-free. The r...
