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-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.
