What to Know

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.

What to Do

Monitor Linux's web page for any future patch releases.
