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.

SA-18 Tamper Resistance and Detection
addresses: CWE-354

Proper validation of integrity check values is required for reliable tamper detection, directly reducing undetected modification risks.

SC-21 Secure Name/Address Resolution Service (Recursive or Caching Resolver)
addresses: CWE-354

Requires validation of integrity check values on every resolution response, directly mitigating tampered or corrupted DNS data.

SC-33 Transmission Preparation Integrity
addresses: CWE-354

Control mandates proper validation of integrity values (checksums) on prepared data, making flawed validation of those checks ineffective for attackers.

SI-7 Software, Firmware, and Information Integrity
addresses: CWE-354

Requires use of proper integrity verification tools, reducing the chance an incorrect check value is accepted.

SR-9 Tamper Resistance and Detection
addresses: CWE-354

Requires proper validation of integrity mechanisms, directly mitigating flawed check-value handling.
