CWE-1431 Detail

The product uses a hardware module implementing a cryptographic algorithm that writes sensitive information about the intermediate state or results of its cryptographic operations via one of its output wires (typically the output port containing the final result).

Vulnerability Mapping Notes

Justification : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Comment : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
