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.
Retention policies enforce removal or sanitization of sensitive data before storage or transfer per regulatory requirements.
The generate-on-demand-and-delete requirement enforces removal of sensitive information before storage or transfer, preventing improper retention.
Requires explicit removal of sensitive information prior to component transfer or disposal, reducing exposure from retained data.
Eradication of spilled information from contaminated systems mitigates the effects of improper removal of sensitive data before storage or transfer.
The control requires verified removal of sensitive data before media is made available at a reduced classification level, directly addressing improper removal prior to storage or transfer.
Explicit procedures to delete inaccurate or outdated PII directly mitigate improper removal of sensitive information before storage or transfer.
Mandates complete sanitization during cleanup so that shared resources (memory, caches, buffers) do not retain data across subjects.
Termination of the non-persistent artifact guarantees cleanup of temporary state, directly countering incomplete cleanup weaknesses.
