Official description

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
