Mitigating Controls
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.
Key generation under controlled management uses approved random-bit sources rather than insufficiently random values.
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.
Cryptographic controls require use of approved, sufficiently random values for keys and nonces.
Secure SDLC processes include verification steps that can catch insufficient randomness but do not directly specify RNG requirements.
Secure coding standards explicitly prohibit use of weak or predictable random number generators.
Security testing can detect weak randomness but does not prescribe the control itself.
Secure authentication mechanisms depend on unpredictable values (nonces, salts, session tokens) to resist guessing.
Hardening callouts derived
DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.
