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 require bounds-checked pointer arithmetic and static analysis to prevent out-of-range offsets.

ID.RA-01 partial match
prevents

SAST/DAST tools used for vulnerability identification can surface this class of coding defect.

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

Security testing can detect out-of-range pointer offsets before release.

A.8.25 Secure development life cycle partial match
prevents

Secure SDLC mandates input validation and bounds checking that can prevent out-of-range pointer offsets.

A.8.26 Application security requirements partial match
prevents

Application security requirements include memory-safety rules that reduce pointer-offset errors.

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

Secure architecture principles promote safe pointer handling and memory layout controls.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly forbid unsafe pointer arithmetic and require bounds checks.
