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 prevent incorrect calculations via reviews, testing, and verification in security-critical code.

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

Security testing in development and acceptance can detect calculation flaws before deployment.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle mandates verification steps that catch incorrect calculations before they reach production.

A.8.26 Application security requirements partial match
prevents

Application security requirements can explicitly call for numeric accuracy and bounds checking.

A.8.27 Secure system architecture and engineering principles partial match
degrades

Secure architecture principles include input validation and safe arithmetic design that reduce calculation errors.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly prohibit unsafe arithmetic and require defensive checks against incorrect results.
