CVE-2017-1000380

Published: 17 June 2017

sound/core/timer.c in the Linux kernel before 4.11.5 is vulnerable to a data race in the ALSA /dev/snd/timer driver resulting in local users being able to read information belonging to other users, i.e., uninitialized memory contents may be disclosed when a read and an ioctl happen at the same time.

From the Ubuntu Security Team

Alexander Potapenko discovered a race condition in the Advanced Linux Sound Architecture (ALSA) subsystem in the Linux kernel. A local attacker could use this to expose sensitive information (kernel memory).
