In the Linux kernel, the following vulnerability has been resolved:
ASoC: DPCM: Don't pick up BE without substream
When DPCM tries to add valid BE connections at dpcm_add_paths(), it
doesn't check whether the picked BE actually supports for the given
stream direction. Due to that, when an asymmetric BE stream is
present, it picks up wrongly and this may result in a NULL dereference
at a later point where the code assumes the existence of a
corresponding BE substream.
This patch adds the check for the presence of the substream for the
target BE for avoiding the problem above.
Note that we have already some fix for non-existing BE substream at
commit 6246f283d5e0 ("ASoC: dpcm: skip missing substream while
applying symmetry"). But the code path we've hit recently is rather
happening before the previous fix. So this patch tries to fix at
picking up a BE instead of parsing BE lists.
