In the Linux kernel, the following vulnerability has been resolved:
s390/vfio_ccw: Ensure first IDAW remains constant
The first IDAW in a list does not need to be on a 2K/4K boundary
like all others, and so is read separately to accurately calculate
the size of the buffer needed to read the full IDAL.
