Frequently Asked Questions

Which systems are exposed to this issue?

Systems using the Linux kernel with the AMDGPU DRM driver are relevant. The affected condition occurs when the driver does not support atomic modesetting.

What is required to trigger the problem?

The issue is triggered in the non-atomic driver path when framebuffer handling accesses plane->state->fb instead of plane->fb. This can result in a null-pointer panic.

What is the impact if the issue is triggered?

The described impact is a DRM panic caused by a null-pointer access, which can crash the affected kernel.

How can the issue be remediated?

Apply a kernel update containing the referenced stable fixes. The fix uses plane->fb for framebuffer access when the driver does not support atomic modesetting.
