Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

在 Linux 内核中，以下漏洞已得到修复： drm/amdgpu/gfx6: 在计算队列中也使用 PFP 在 GFX6 架构中，计算环（compute rings）与图形环（graphics ring）使用相同的命令处理器（CP）路径。两者唯一的区别在于计算环不支持绘制（draw）指令。（这与 GFX7 及更新架构不同，GFX7 及以上架构为计算队列配备了独立的指令解析器，称为 MEC。） 这意味着在 GFX6 上，必须考虑到计算队列中同样存在 PFP（Packet Fragment Processor）： 在图

Vulnerability Title
drm/amdgpu/gfx6: Use PFP on the compute queues too
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/gfx6: Use PFP on the compute queues too On GFX6, the compute rings use the same CP path as the graphics ring. The only difference is that they don't support draw commands. (As opposed to GFX7 and newer which have a separate command parser that is called MEC for compute queues.) This means that we have to take into consideration that the PFP also exists on compute queues on GFX6: Use PFP for register writes on both graphics and compute queues. In the pipeline sync, use the PFP to wait for the previous fence (and not the ME) to prevent the PFP from starting to execute the next submission while the ME is still in the previous submission. After a VM flush, emit PFP_SYNC_ME on compute queues as well.
