Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and static/dynamic analysis directly find functions that return stack-variable addresses.

Requiring documented development standards and tools can embed coding rules that forbid returning addresses of automatic variables.

Secure engineering principles include memory-safety and lifetime rules that structurally disallow returning addresses of stack locals.

Input validation can structurally reject or sanitize data that would otherwise trigger an out-of-bounds write.

Memory-protection mechanisms limit the exploitability and blast radius of a successful out-of-bounds write.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly prevent return of stack addresses via static analysis, code review, and compiler checks.

ID.RA-01 partial match
prevents

Vulnerability scanning and recording can discover out-of-bounds write flaws so they can be remediated.

PR.PS-02 partial match
prevents

Patching or replacing vulnerable software directly eliminates known instances of this coding weakness.

finds

Security testing in development can detect use-after-return bugs before release.

prevents

Secure SDLC practices can catch stack-variable misuse during design and code review.

prevents

Application security requirements can specify bounds-checking and safe memory handling.

degrades

Secure architecture and engineering principles discourage unsafe stack usage patterns.

prevents

Secure coding standards directly prohibit returning addresses of stack variables.

prevents

Change management can enforce review gates that catch unsafe memory operations before deployment.
