A use-after-free flaw was found in the Linux kernel’s sound subsystem in
the way a user triggers concurrent calls of PCM hw_params. The hw_free
ioctls or similar race condition happens inside ALSA PCM for other ioctls.
This flaw allows a local user to crash or potentially escalate their
privileges on the system.
