CWEs ranked by how often they appear in real CVEs. The rationale describes how this control reduces exploitability of each weakness class.

CWE Name CVEs Why this control addresses it
CWE-754Improper Check for Unusual or Exceptional Conditions697Implements detection of unusual or exceptional conditions followed by safe mode entry, reducing the window for exploitation of unchecked conditions.
CWE-755Improper Handling of Exceptional Conditions662Supplies a concrete handling action (safe mode) for exceptional conditions, mitigating risks from improper or absent handling that could allow continued attacks.
CWE-703Improper Check or Handling of Exceptional Conditions146Provides a defined response to detected conditions by restricting operation, ensuring exceptional conditions are handled rather than ignored or mishandled.
CWE-636Not Failing Securely ('Failing Open')27Entering safe mode when conditions are detected prevents failing open and continuing normal operation in a potentially exploitable state.
