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.

SC-10 Network Disconnect
addresses: CWE-772

Ensures network resources are released once the session ends or becomes inactive, closing the window for missing-release weaknesses.

Mitigating Controls (NIST CSF 2.0) AI

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.

ID.AM-08 mostly match
prevents

Lifecycle management explicitly requires handling resources through end-of-life including release.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly prevent missing resource-release defects during development.

DE.CM-09 partial match
prevents

Runtime monitoring may surface resource-exhaustion symptoms but does not address release logic.

PR.IR-04 partial match
prevents

Capacity monitoring can detect exhaustion caused by unreleased resources but does not prevent the root defect.

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.

A.8.10 Information deletion mostly match
degrades

Explicit information-deletion requirements directly address timely release of resources after use.

A.8.25 Secure development life cycle partial match
prevents

Secure-SDLC practices include resource-management reviews, yet the control covers the entire lifecycle, not just this weakness.

A.8.28 Secure coding partial match
prevents

Secure-coding rules can mandate explicit resource-release patterns, but the control is broader than this single weakness.

A.8.32 Change management none match
detects

Change-management processes may catch missing de-allocation during reviews, but the control itself does not target resource lifetime.

A.8.9 Configuration management none match
none

Configuration baselines can enforce resource limits or timeouts, indirectly reducing exposure to leaks.
