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 include coding standards and reviews that prevent TOCTOU race conditions.

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.8.29 Security testing in development and acceptance mostly match
detects

Security testing can detect race conditions and locking errors before release.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle includes concurrency and locking requirements that reduce improper locking defects.

A.8.26 Application security requirements partial match
prevents

Application security requirements can mandate proper lock acquisition/release patterns.

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

Secure architecture principles address thread-safety and resource synchronization.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly prohibit missing or incorrect lock usage.

A.8.32 Change management partial match
prevents

Change management may catch locking issues introduced by modifications but does not prevent the weakness itself.
