Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SC-4 Information in Shared System Resources good match

prevent

Prevents unauthorized information transfer via shared system resources such as GPU registers accessible by both secure workloads and non-secure applications.

AC-4 Information Flow Enforcement good match

prevent

Enforces information flow control policies to block exfiltration of sensitive intermediate register values from secure to non-secure environments.

AC-3 Access Enforcement good match

prevent

Mandates enforcement of access authorizations to restrict non-secure applications from accessing secure workload register values.

MITRE ATT&CK Enterprise TechniquesAI

T1005 Data from Local System Collection

Adversaries may search local system sources, such as file systems, configuration files, local databases, virtual machine files, or process memory, to find files of interest and sensitive data prior to Exfiltration.

Why these techniques?

Vulnerability enables remote exploitation to access/exfil sensitive register data from secure GPU workloads (T1005) via network-accessible driver interfaces (T1190).

Confidence: MEDIUM · MITRE ATT&CK Enterprise v18.1

NVD Description

Intermediate register values of secure workloads can be exfiltrated in workloads scheduled from applications running in the non-secure environment of a platform.

Deeper analysisAI

CVE-2025-25176 is a high-severity vulnerability (CVSS 9.1, CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N) in GPU drivers from Imagination Technologies, published on 2026-01-13. It enables the exfiltration of intermediate register values from secure workloads when those workloads are scheduled by applications running in the non-secure environment of a platform. The issue is classified under CWE-668 (Exposure of Resource to Wrong Sphere).

Unauthenticated attackers can exploit this vulnerability remotely over the network with low attack complexity and no user interaction required. By scheduling workloads from a non-secure application, they can access and exfiltrate sensitive intermediate register values from secure workloads, resulting in high confidentiality and integrity impacts without affecting availability.
