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.

SI-16 Memory Protection
addresses: CWE-787

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

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 require bounds checking and input validation that prevent out-of-bounds buffer accesses.

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.

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

Security testing in development can detect buffer-overrun defects before release.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle includes buffer-handling practices that reduce out-of-bounds accesses.

A.8.26 Application security requirements partial match
prevents

Application security requirements can mandate bounds checking and safe memory APIs.

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

Secure architecture principles discourage unsafe pointer arithmetic and unbounded buffers.

A.8.28 Secure coding partial match
prevents

Secure coding standards directly forbid writing or reading past buffer ends.

A.8.32 Change management partial match
prevents

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