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.
AnalysisAI
Memory corruption in the Linux kernel's AF_ALG crypto subsystem allows local authenticated users to execute arbitrary code or cause denial of service through a page reassignment overflow in af_alg_pull_tsgl. The vulnerability affects multiple stable kernel branches (4.14 through 7.0) and has been patched across all maintained versions. …
