CVE-2017-13167
A race condition was found in the Linux kernel's sound timer code in the snd_timer_user_read() function in the sound/core/timer.c file. An unprivileged attacker can exploit the race condition to cause an out-of-bound access which may lead to a system crash or other unspecified impact. Due to the nature of the flaw, privilege escalation cannot be fully ruled out.
