In the Linux kernel, the following vulnerability has been resolved:
ASoC: SOF: Don't allow pointer operations on unconfigured streams
When reporting the pointer for a compressed stream we report the current
I/O frame position by dividing the position by the number of channels
multiplied by the number of container bytes. These values default to 0 and
are only configured as part of setting the stream parameters so this allows
a divide by zero to be configured. Validate that they are non zero,
returning an error if not
