A race condition flaw was found in the Linux kernel sound subsystem due to
improper locking. It could lead to a NULL pointer dereference while
handling the SNDCTL_DSP_SYNC ioctl. A privileged local user (root or member
of the audio group) could use this flaw to crash the system, resulting in a
denial of service condition
