Description
In the Linux kernel, the following vulnerability has been resolved:
s390/vfio_ccw: Ensure index for read/write regions are within range
The introduction of the capability chain rightly clamped the
region indexes to the range of the capabilities itself, but
neglected to do so for the existing read/write regions which
should also be enforced.
