Systems booted with shim have a Forbidden Signature Database called mokx. During boot, hashes and certs contained within the mokx are loaded into the blacklist keyring. When calling verify_pkcs7_message_sig the contents of the blacklist keyring (or revocation list) are referenced when validating keys on the platform keyring. Currently, when validating against the secondary or builtin keyrings, the revocation list is not referenced. Move up the check to allow the revocation list to be used with all keyrings, including the secondary and builtin, allowing the system owner to take corrective action should a vulnerability be found within keys contained within either keyring.
