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

ASoC: SOF: Add some bounds checking to firmware data

Smatch complains about "head->full_size - head->header_size" can
underflow. To some extent, we're always going to have to trust the
firmware a bit. However, it's easy enough to add a check for negatives,
and let's add a upper bounds check as well.
