Design checks should be performed to identify any uninitialized flip-flops used for security-critical functions.
Phases : Architecture and Design
All registers holding security-critical information should be set to a specific value on reset.

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.
