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.

DE.CM-09 partial match
blocks

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

ID.AM-08 partial match
blocks

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

PR.IR-04 partial match
blocks

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

PR.PS-06 partial match
blocks

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