¿Estoy en riesgo?
Dependiendo de su situación, la tabla a continuación responde si un atacante en una posición determinada puede extraer datos de un objetivo concreto. La columna "Usaurio → Kernel" también se aplica dentro de una máquina virtual (usuario de VM vs. kernel de VM), ya que los mismos mecanismos de CPU están en juego independientemente de la virtualización.
