Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-787

Out-of-bounds writes that corrupt control flow or inject shellcode are rendered non-executable by the same memory protections.

PR.PS-06 mostly match
prevents

Secure-development practices directly prevent introduction of stack buffer overflows.

ID.RA-01 partial match
prevents

Vulnerability scanning can discover stack buffer overflows but does not prevent their introduction.

PR.PS-02 partial match
prevents

Patching eliminates known instances of the weakness after discovery.

detects

Security testing (fuzzing, static analysis) detects stack overflows before release.

prevents

Secure SDLC mandates buffer-safety practices that directly prevent stack overflows.

prevents

Application security requirements can specify buffer-size and input-validation rules.

prevents

Secure architecture principles include memory-safety and least-privilege stack usage.

prevents

Secure coding standards explicitly forbid unsafe buffer handling that causes CWE-121.

prevents

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