Description: | In the Linux kernel 4.12, 3.10, 2.6 and possibly earlier versions a race condition vulnerability exists in the sound system, this can lead to a deadlock and denial of service condition. Luo Quan and Wei Yang discovered that a race condition existed in the Advanced Linux Sound Architecture (ALSA) subsystem of the Linux kernel when handling ioctl()s. A local attacker could use this to cause a denial of service (system deadlock).
