CVE-2025-38352 posix-cpu-timers: fix race between handle_posix_cpu_timers() and posix_cpu_timer_del()

In the Linux kernel, the following vulnerability has been resolved: posix-cpu-timers: fix race between handleposixcputimers and posixcputimerdel If an exiting non-autoreaping task has already passed exitnotify and calls handleposixcputimers from IRQ, it can be reaped by its parent or debugger rig...

CVE-2025-38352

CVE-2025-38352: In the Linux kernel, a TOCTOU race affects posix-cpu-timers between handle_posix_cpu_timers() and posix_cpu_timer_del() when an exiting non-autoreaping task runs from IRQ. The fix adds a tsk->exit_state check into run_posix_cpu_timers() to prevent misdetection of timer->it.c...

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...
