Description
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. Patched in https://github.com/pyca/cryptography/pull/10423
