Description
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.
A vulnerability has been identified in the Linux kernel's af_alg component, specifically within the page reassignment process of the af_alg_pull_tsgl function. This issue arises because the original loop handling page reassignment was not properly updated, leading to the potential reassignment of one extra page than necessary. The vulnerability is present in the Linux kernel stable tree.
Users can apply the latest patches available in the Linux kernel stable tree to address this vulnerability.
