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.

AT-5 Contacts with Security Groups and Associations
addresses: CWE-338

Security associations share details on cryptographically weak PRNGs, helping avoid their implementation in security-critical functions.

SC-12 Cryptographic Key Establishment and Management
addresses: CWE-338

Cryptographic key management standards require cryptographically strong PRNGs for key material, blocking use of weak generators.
