Description Summary:
The Linux kernel amdgpu VCE driver allows partial address patches, which can result in the firmware writing to invalid or malicious memory addresses.
Executive Summary:
A vulnerability in the Linux kernel amdgpu VCE driver could allow a local attacker to cause memory corruption or influence firmware operations.
Vulnerability Details
CVE-ID: CVE-2026-53375
Affected Software: Linux Kernel
Affected Versions: Linux kernel versions prior to 4.2; fixed in 6.1.175, 6.6.140, 6.12.90, and 6.18.32.
Vulnerability: This is a memory corruption vulnerability in the drm/amdgpu/vce driver component. The issue stems from improper handling of partial address patches, allowing a low-privileged local user (PR:L) to trigger writes to invalid addresses within the firmware.
Business Impact
The CVSS score of 8.8 reflects the high risk of this vulnerability. Successful exploitation could lead to privilege escalation or a crash of the graphics subsystem, potentially affecting overall system stability and data integrity.
Remediation Plan
Immediate Action: Update the Linux kernel to version 6.1.175, 6.6.140, 6.12.90, 6.18.32, or later stable releases.
Proactive Monitoring: Monitor logs for VCE firmware errors or unexpected hardware exceptions related to the amdgpu driver.
Compensating Controls: Enforce the principle of least privilege for local users to limit the ability to interact with vulnerable graphics drivers.
Exploitation Status
Public Exploit Available: No
Analyst Notes: As of July 21, 2026, there is no public information indicating active exploitation or a public proof-of-concept for this vulnerability. The flaw is a technical implementation error within the address patching logic of the VCE driver.
Analyst Recommendation
System administrators must prioritize updating the Linux kernel on all machines utilizing AMD VCE hardware. Because this vulnerability allows for kernel-level memory manipulation, immediate application of the vendor-provided security patches is required.
