CVE-2026-39892

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...

Cryptography vulnerable to buffer overflow if non-contiguous buffers were passed to APIs

If a non-contiguous buffer was passed to APIs which accepted Python buffers e.g. Hash.update, this could lead to buffer overflows. For example: python h = HashSHA256 b.updatebuf::-1 would read past the end of the buffer on Python 3.11...
