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.
Mandates complete sanitization during cleanup so that shared resources (memory, caches, buffers) do not retain data across subjects.
Operational retention schedules mandate complete cleanup of temporary or residual sensitive data after use.
Termination of the non-persistent artifact guarantees cleanup of temporary state, directly countering incomplete cleanup weaknesses.
Fail-safe procedures can explicitly require cleanup of temporary state, resources, or privileges on failure to avoid leaving the system in an inconsistent state.
The explicit delete step when information is no longer needed implements the cleanup that this weakness omits.
Enforces complete cleanup and sanitization steps during disposal, closing gaps that leave data remnants on retired components.
