The CWE Content Team conducted in-depth research and analysis in the following areas:
Hardware: identified overlapping/duplicate issues, which will need community consultation to resolve. Also investigating a different way to organize entries
besides the hardware view (CWE-1194), and adding Functional_Area elements related to Power and Clock.
Cryptography/randomness subtree analysis (CWE-330): the team began investigating how to describe
randomness, entropy, and unpredictability in a consistent way and created a new Base (CWE-1204) prompted by community feedback about CWE-329.
More changes for randomness are planned, and the CWE research community will be consulted for important decisions.
Root cause analysis for access of unintialized memory: this led to updates to several entries, with more demonstrative and observed examples, and identified
the need to clarify differences between CWE-456 and CWE-457, and possibly deprecate CWE-456 in the future.
Maintenance view: created new maintenance view (CWE-1081) to make it easier for CWE users to
anticipate future changes. Reviewed and updated maintenance notes for over 130 entries.
Content checks: improved checks for invalid or inconsistent content, such as relationship gaps (e.g., a Class being a parent of a Variant), incorrect relationships
(e.g., a Weakness that is a “ChildOf” a category), or entries where more than one relationship is labeled “Primary”. This work will be ongoing.
