The vulnerability allows a local attacker to obtain potentially sensitive information.
The vulnerability exists in the sound/core/timer.c code due to a race condition that exists in the timing functionality of the ALSA/dev/snd/timer driver when a read and an ioctl system call happens simultaneously.
