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 enforce proper memory allocation/deallocation via coding standards, reviews, and tooling.

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
finds

Security testing in development can detect unreleased memory, providing partial coverage of the weakness.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle mandates memory-management practices that reduce missing-release defects.

A.8.26 Application security requirements partial match
prevents

Application security requirements can specify explicit memory-release rules, partially mitigating the weakness.

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

Secure system architecture and engineering principles include resource-management guidelines that address memory leaks.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly require proper allocation/deallocation, covering most of this weakness.

A.8.6 Capacity management partial match
finds

Capacity management may detect memory exhaustion symptoms but does not prevent the coding flaw.
