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-459

Mandates complete sanitization during cleanup so that shared resources (memory, caches, buffers) do not retain data across subjects.

addresses: CWE-459

Operational retention schedules mandate complete cleanup of temporary or residual sensitive data after use.

addresses: CWE-459

Termination of the non-persistent artifact guarantees cleanup of temporary state, directly countering incomplete cleanup weaknesses.

addresses: CWE-459

Fail-safe procedures can explicitly require cleanup of temporary state, resources, or privileges on failure to avoid leaving the system in an inconsistent state.

addresses: CWE-459

The explicit delete step when information is no longer needed implements the cleanup that this weakness omits.

addresses: CWE-459

Enforces complete cleanup and sanitization steps during disposal, closing gaps that leave data remnants on retired components.

PR.PS-06 mostly match
prevents

Secure-development practices and coding standards normally require proper resource release and cleanup.

ID.AM-08 partial match
prevents

Life-cycle management encompasses disposal of temporary resources but does not specifically target runtime cleanup bugs.

PR.DS-10 partial match
prevents

Explicitly calls for removing sensitive data after use, directly addressing one class of incomplete cleanup.

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.

degrades

Explicitly requires secure deletion of temporary or residual data, directly addressing incomplete cleanup.

prevents

SDLC practices include cleanup steps, yet the weakness can still occur if those steps are omitted.

prevents

Secure-coding rules can mandate explicit cleanup of temporary resources, but do not guarantee it.

finds

Change-management processes may require cleanup verification, but the control itself does not address the weakness.
