What to Know

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

crypto: af_alg - Fix page reassignment overflow in af_alg_pull_tsgl

When page reassignment was added to af_alg_pull_tsgl the original

loop wasn't updated so it may try to reassign one more page than

necessary.

Add the check to the reassignment so that this does not happen.

Also update the comment which still refers to the obsolete offset

argument. (NVD)

What to Do

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