Summary		(es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: drm/amdgpu/pm: corrige la desreferencia del puntero NULL cuando se obtiene el límite de energía. Debido a que la inicialización de powerplay_table se omite en el caso sriov, verificamos y configuramos el valor OD inferior y superior predeterminado si powerplay_table es NULL.
