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.
