NIST 800-53 r5 controls PROPOSED for this weakness (1)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-12`	Cryptographic Key Establishment and Management	SC	graded partial Managed key generation relies on PRNGs seeded and operated with adequate entropy, avoiding the listed weakness.
