In the Linux kernel, the following vulnerability has been resolved:
ring-buffer: Add checking nr subbufs to persistent ring buffer validation
Sashiko reported that the code was using meta->nr subbufs without making
sure that it matched the nr pages + 1 on data that was assuming the two
were the same.
Add a check to the persistent ring buffer validation code to make sure
that the saved nr subbufs matches what we expect.
