PR.PS-06 mostly match
prevents

Secure SDLC practices directly prevent mismatched alloc/free via code review and static analysis, but fixing this single CWE only partially fulfills the broad control.

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

Security testing in development can detect mismatched alloc/free pairs before release.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle mandates consistent allocation/deallocation patterns that prevent mismatched memory routines.

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

Secure system architecture and engineering principles require use of matching allocators and deallocators.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly prohibit mismatched memory-management calls and enforce safe patterns.
