Summary

CVE-2025-29946 is a medium-severity Insufficient or Incomplete Data Removal within Hardware Component (CWE-1301) vulnerability in Amd (inferred from references). Its CVSS base score is 4.5 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Data from Local System (T1005); ranked at the 4th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to MP-6 (Media Sanitization) and SR-12 (Component Disposal) — see the control section below for these in your framework.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

MP-6 Media Sanitization good match

MP-6 requires sanitization of media/hardware before disposal or reuse, directly stopping incomplete data removal.

SR-12 Component Disposal good match

SR-12 mandates specific disposal techniques for components that include complete data erasure.

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.

ID.AM-08 mostly match
prevents

Lifecycle management of hardware explicitly includes secure decommissioning and data sanitization steps.

PR.PS-03 mostly match
prevents

Hardware removal/replacement policies directly require complete data erasure before disposition.

PR.DS-10 partial match
prevents

Example explicitly calls for removal of confidential data from memory/hardware contexts.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

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.7.14 Secure disposal or re-use of equipment full match
degrades

Directly requires secure disposal or re-use of equipment to ensure data is completely removed.

A.8.10 Information deletion full match
degrades

Mandates procedures for secure information deletion that would prevent incomplete hardware data removal.

A.5.11 Return of assets partial match
mitigates

Return-of-assets process can include verification of data removal but does not specify technical completeness.

A.5.12 Classification of information none match
none

Classification helps identify sensitive data that must be removed but does not address removal completeness.

A.5.33 Protection of records none match
none

Protection of records implies proper disposal but does not prescribe hardware-level removal methods.
