What is the CVSS score of EUVD-2026-45526?

EUVD-2026-45526 has a CVSS 3.1 base score of 7.8 (High). CVSS vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H. EPSS exploitation probability: 0.2%.

Which versions of Linux are affected by EUVD-2026-45526?

AMD's amdgpu JPEG v5.0.0 driver contains a local privilege escalation vulnerability allowing unprivileged users with GPU device access to escalate privileges and corrupt kernel memory.. A patch is available.

How to fix or mitigate EUVD-2026-45526?

Within 24 hours, inventory all systems running the amdgpu driver through asset management systems and identify which host the vulnerable v5.0.0 version. Within 7 days, obtain the patched driver version from AMD security advisories and conduct compatibility testing in non-production environments. Within 30 days, systematically deploy the patched driver across all affected systems, prioritizing those where non-administrative users have GPU render node access, and verify successful deployment through kernel and driver logs.

DescriptionCVE.org

In the Linux kernel, the following vulnerability has been resolved:

drm/amdgpu/jpeg: set no_user_fence for JPEG v5.0.0 ring

JPEG rings do not support 64-bit user fence writes, reject CS submissions with user fences.

(cherry picked from commit 0f43893d3cd478fa57836697525b338817c9c23d)

AnalysisAI

Local privilege escalation and memory corruption in the Linux kernel's amdgpu JPEG v5.0.0 driver allows a low-privileged local user with access to the GPU render node to submit command-stream (CS) requests carrying a 64-bit user fence that the JPEG ring cannot service, corrupting kernel/GPU-writable memory. The fix makes the driver set no_user_fence and reject such submissions. This is a CVSS 7.8 (AV:L) issue with a very low EPSS (0.17%, 6th percentile) and no public exploit identified at time of analysis; it is patched upstream.
