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

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 directly enforce use of cryptographically strong RNGs and catch insufficient randomness during design, coding, and testing.

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

Cryptographic controls require use of approved, sufficiently random values for keys and nonces.

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

Security testing can detect weak randomness but does not prescribe the control itself.

A.8.25 Secure development life cycle partial match
prevents

Secure SDLC processes include verification steps that can catch insufficient randomness but do not directly specify RNG requirements.

A.8.28 Secure coding partial match
prevents

Secure coding standards explicitly prohibit use of weak or predictable random number generators.

A.8.5 Secure authentication partial match
degrades

Secure authentication mechanisms depend on unpredictable values (nonces, salts, session tokens) to resist guessing.
