Descriptions

In the Linux kernel, the following vulnerability has been resolved:

drm/amdgpu: amdgpu_ttm_gart_bind set gtt bound flag

Otherwise after the GTT bo is released, the GTT and gart space is freed
but amdgpu_ttm_backend_unbind will not clear the gart page table entry
and leave valid mapping entry pointing to the stale system page. Then
if GPU access the gart address mistakely, it will read undefined value
instead page fault, harder to debug and reproduce the real issue.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: drm/amdgpu: amdgpu_ttm_gart_bind establece el indicador vinculado a gtt. De lo contrario, después de que se libera GTT bo, se libera el espacio GTT y gart, pero amdgpu_ttm_backend_unbind no borrará la entrada de la tabla de páginas de gart y dejará una asignación válida. entrada que apunta a la página del sistema obsoleto. Luego, si la GPU accede a la dirección de Gart por error, leerá un valor indefinido en lugar de un error de página, lo que será más difícil de depurar y reproducir el problema real.
