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

Security testing in development and acceptance can detect uninitialized resource usage through dynamic analysis and fuzzing.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle mandates initialization checks and static analysis that can catch uninitialized resource use.

A.8.26 Application security requirements partial match
prevents

Application security requirements can specify mandatory initialization of variables and resources before use.

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

Secure system architecture and engineering principles include defensive coding practices that prevent use of uninitialized memory or objects.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly require explicit initialization of all variables and resources, substantially mitigating CWE-908.
