Name: Missing Security-Relevant Feedback for Unexecuted Operations in Hardware Interface

The product has a hardware interface that silently discards operations in situations for which feedback would be security-relevant, such as the timely detection of failures or attacks.

Open source silicon root of trust (RoT) product does not immediately report when an integrity check fails for memory requests, causing the product to accept and continue processing data [REF-1468]

Potential Mitigations

Phases : Architecture and Design
Phases : Implementation

Detection Methods

Automated Static Analysis - Source Code

Effectiveness : High

Manual Static Analysis - Source Code

Effectiveness : Moderate

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.
