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.
In the Linux kernel versions 4.12, 3.10, 2.6, and possibly earlier, a race condition vulnerability exists in the sound system allowing for a potential deadlock and memory corruption due to use-after-free condition and thus denial of service. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is unlikely.
