cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. From 45.0.0 to before 46.0.7, if a non-contiguous buffer was passed to APIs which accepted Python buffers (e.g. Hash.update()), this could lead to buffer overflows. This vulnerability is fixed in 46.0.7.

The remote Fedora 44 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2026-aa318887d6 advisory.
