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 buffer underflows via safe coding, bounds checks, and analysis, but eliminating only this CWE covers a narrow slice of the control's broader intent.

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

Security testing in development can detect and eliminate pre-buffer memory accesses before release.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle includes buffer-boundary checks that reduce out-of-bounds reads before buffer start.

A.8.26 Application security requirements partial match
prevents

Application security requirements can mandate bounds checking and pointer validation to prevent pre-buffer accesses.

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

Secure architecture principles promote safe memory handling and pointer arithmetic safeguards.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly require bounds checking and pointer validation that prevent this weakness.
