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-8 Transmission Confidentiality and Integrity
addresses: CWE-924

The control directly mandates integrity protection for transmitted information, addressing failures to enforce message integrity in transit.

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.DS-02 full match
prevents

Directly requires integrity protection (e.g., signatures/hashes) for data-in-transit, which prevents the described weakness while also addressing confidentiality/availability.

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.8.20 Networks security mostly match
prevents

Mandates network security controls that can enforce message integrity on channels.

A.8.21 Security of network services mostly match
prevents

Addresses security of network services, which may include integrity mechanisms.

A.8.24 Use of cryptography mostly match
prevents

Cryptography is the primary technical means to enforce message integrity during transmission.

A.5.14 Information transfer partial match
prevents

Requires secure information transfer procedures that can include integrity checks.

A.8.26 Application security requirements partial match
prevents

Application security requirements can specify integrity protection for transmitted messages.
