- In the Linux kernel, the following vulnerability has been resolved: fs/proc: do_task_stat: use
sig->stats_lock to gather the threads/children stats lock_task_sighand() can trigger a hard lockup. If
NR_CPUS threads call do_task_stat() at the same time and the process has NR_THREADS, it will spin with
