WDDM 2.0 gpummu is supposed to ensure that the memory has been zeroed between different applications that use virtual GPU memory.<p>If this is the case there might be a compliance issue on nVidia side which makes me wonder if webgl is vulnerable also.<p>WebGL was amended to request a zero when provisioning or disposing of a buffer but it relies on the API which is handled by the driver if nVidia is taking some shortcuts to save time it might be possible to leech stale memory this way.
