…ent Driver May Cause a DoS Invalid data is passed to the NXP Plug & Trust Nano Package used by the NuttX secure element driver. If the NXP code is not handling the malformed data, a corruption can occur. Alternatively, if the attacker is able to point create_signature_args->algorithm in memory at an address that is not accessible, a crash can occur. Applicable to: * `signature_algorithm_mapping[create_signature_args->algorithm]` * `signature_algorithm_mapping[verify_signature_args->algorithm]` Signed-off-by: Catalin Visinescu <catalin_visinescu@yahoo.com>
