Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Directly mitigates the CVE by requiring timely identification, reporting, and patching of the vulnerable Imagination Technologies GPU driver.

AC-6 Least Privilege good match

prevent

Enforces least privilege to prevent non-privileged user software from conducting improper read/write operations on critical DMA buffers.

SC-4 Information in Shared System Resources good match

prevent

Protects information in shared system resources like DMA buffers from unauthorized access and transfer by low-privileged users.

NVD Description

Software installed and run as a non-privileged user may conduct improper read/write operations on imported/exported DMA buffers.

Deeper analysisAI

CVE-2024-46974 affects the Imagination Technologies GPU driver, where software installed and run as a non-privileged user can conduct improper read/write operations on imported/exported DMA buffers. This vulnerability, published on 2025-01-31, is linked to CWE-266 (Incorrect Privilege Assignment for Critical Resource) and CWE-274 (Improper Handling of Insufficient Privileges or Quota). It carries a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to significant impacts on confidentiality, integrity, and availability.

A local attacker with low privileges can exploit this issue through low-complexity means without requiring user interaction. Exploitation allows improper access to DMA buffers, potentially enabling arbitrary read/write operations that compromise system security, data exposure, modification of critical resources, or denial of service.
