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.
Secure SDLC practices directly prevent buffer-size miscalculations via coding standards, reviews, and testing, while fixing this single weakness only partially fulfills the broader control.

Secure coding standards directly require correct buffer-size calculations.
Security testing can detect buffer-size errors before release.
Secure development lifecycle mandates size-checking practices that reduce buffer-size miscalculations.
Application security requirements can specify buffer-size validation rules.
Secure architecture principles include safe memory-allocation guidelines.
