Vulnerability Data

On Microchip RN4870 devices, when more than one consecutive PairReqNoInputNoOutput request is received, the device becomes incapable of completing the pairing process. A third party can inject a second PairReqNoInputNoOutput request just after a real one, causing the pair request…

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match

Input validation directly enforces completeness checks on supplied elements before they are accepted for processing.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require robust input validation and error handling for incomplete or malformed elements.

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.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect incomplete-element handling but does not itself prevent the weakness in production code.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle requires input validation and completeness checks that reduce incomplete-element handling failures.

A.8.26 Application security requirements partial match
prevents

Application security requirements can mandate handling of incomplete or malformed inputs, mitigating this weakness.

A.8.28 Secure coding partial match
prevents

Secure coding standards typically include rules for validating element completeness, directly addressing CWE-239.
