Published Sep 24, 2026
·Updated
In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu/userq: pin mqd and fw object bo to avoid eviction
mqd and fw objects are queue core objects which should remain valid and never be unmapped and evicted for user queues to work properly.
During eviction if these buffers are evicted the hw continue to use the invalid addresses and caused page faults and system hung.

Frequently Asked Questions
1
Which systems are exposed to this issue?
Systems using the Linux kernel amdgpu driver with user queues are relevant. The issue involves queue management descriptor and firmware-object buffers used by those user queues.
2
What failure may occur if the issue is triggered?
If the relevant buffers are evicted while hardware continues using their addresses, the GPU can access invalid addresses. This can cause page faults and a system hang.
