In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: force complete the MES ring fences on reset The MES scheduler ring has no drm scheduler (no_scheduler = true), so it is skipped by the force-completion loop in amdgpu_device_pre_asic_reset(). It uses a polling fence whose hw value lives in wb (GTT) memory and survives a MODE1 reset, while fence_drv.sync_seq keeps advancing for every packet. When the reset is triggered because MES itself stopped responding, the ti…
