{"id":"CVE-2022-48745","summary":"net/mlx5: Use del_timer_sync in fw reset flow of halting poll","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet/mlx5: Use del_timer_sync in fw reset flow of halting poll\n\nSubstitute del_timer() with del_timer_sync() in fw reset polling\ndeactivation flow, in order to prevent a race condition which occurs\nwhen del_timer() is called and timer is deactivated while another\nprocess is handling the timer interrupt.
