Summary
cryptography NULL pointer dereference with pkcs12.serialize_key_and_certificates when called with a non-matching certificate and private key and an hmac_hash override
Details

If pkcs12.serialize_key_and_certificates is called with both:

  1. A certificate whose public key did not match the provided private key
  2. An encryption_algorithm with hmac_hash set (via PrivateFormat.PKCS12.encryption_builder().hmac_hash(...)

Then a NULL pointer dereference would occur, crashing the Python process.

This has been resolved, and now a ValueError is properly raised.
