Description (CNA)

In the Linux kernel, the following vulnerability has been resolved: Revert "drm/amd: flush any delayed gfxoff on suspend entry" commit ab4750332dbe ("drm/amdgpu/sdma5.2: add begin/end_use ring callbacks") caused GFXOFF control to be used more heavily and the codepath that was removed from commit 0dee72639533 ("drm/amd: flush any delayed gfxoff on suspend entry") now can be exercised at suspend again.
