Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

SC-12 Cryptographic Key Establishment and Management
addresses: CWE-330 CWE-331

Key generation under controlled management uses approved random-bit sources rather than insufficiently random values.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 mostly match
prevents

Secure SDLC practices explicitly include vetted RNG and entropy sources, directly preventing this weakness while covering many other development concerns.

PR.AA-03 partial match
prevents

Password-strength policies implicitly require sufficient entropy, but the control addresses authentication rather than algorithmic randomness.

PR.DS-01 partial match
prevents

Proper encryption for data-at-rest requires sufficient entropy for keys/nonces; eliminating the weakness therefore supports but does not fully realize the control.

PR.DS-02 partial match
prevents

Cryptographic protection of data-in-transit depends on adequate entropy; the weakness directly undermines the control's effectiveness.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.24 Use of cryptography mostly match
prevents

Mandates use of cryptography that must rely on sufficient entropy sources.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect insufficient-entropy defects before release.

A.8.25 Secure development life cycle partial match
prevents

Secure-SDLC activities include entropy validation during design and testing.

A.8.28 Secure coding partial match
prevents

Secure-coding rules can explicitly forbid weak random-number generation.

A.8.5 Secure authentication partial match
degrades

Requires secure authentication mechanisms that depend on unpredictable secrets.
