Mitigating Controls

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-665

Ensures shared resources are explicitly initialized or cleared on allocation, preventing exposure of prior contents to new users or processes.

addresses: CWE-665

Mandates that every instance begins in a known (presumably clean) state, eliminating reliance on residual or uninitialized state left by prior executions.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly enforce proper resource initialization during coding and testing.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

detects

Security testing can detect uninitialized variables but does not itself enforce initialization practices.

prevents

Configuration management can enforce secure defaults and initialization settings but is not the primary control for code-level initialization.

prevents

Secure development life cycle mandates initialization checks and secure defaults that directly prevent improper resource initialization.

prevents

Secure system architecture and engineering principles require explicit initialization of resources and secure state management.

prevents

Secure coding standards explicitly forbid uninitialized variables and mandate proper resource initialization before use.
