In the Linux kernel, the following vulnerability has been resolved:
ALSA: hda: Fix possible null-ptr-deref when assigning a stream
While AudioDSP drivers assign streams exclusively of HOST or LINK type,
nothing blocks a user to attempt to assign a COUPLED stream. As
supplied substream instance may be a stub, what is the case when
code-loading, such scenario ends with null-ptr-deref.
