In the Linux kernel, the following vulnerability has been resolved:

ALSA: hda: Fix possible null-ptr-deref when assigning a stream

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.
