NIST 800-53 r5 controls PROPOSED for this weakness (2)AI-assisted

These are model PROPOSALS, not graded mappings. They come from controls_to_cwe_proposals, which carries no grade field at all; across the CWE pages 1,540 of 1,722 such associations (89%) have never been graded by anything. The heading said “address” until 2026-09-29, which asserted a relationship the data does not carry. Graded cross-walks are on the framework map, not here.

Control Title Family Why it addresses this CWE
SC-24Fail in Known StateSCPrevents abrupt termination from uncaught exceptions by requiring a defined, preserved-state failure mode.
SI-17Fail-safe ProceduresSIRequires pre-defined safe responses for uncaught exceptions so they do not result in undefined or insecure program termination.
