Summary
crypto: af_alg - Fix page reassignment overflow in af_alg_pull_tsgl
Details

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

crypto: afalg - Fix page reassignment overflow in afalgpulltsgl

When page reassignment was added to afalgpull_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.
