Esto se debe a que los registros de segmento con un valor de usuario arbitrario pueden generar #GP al ejecutar VERW. Intel SDM vol. 2C documenta el siguiente comportamiento para la instrucción VERW: #GP(0) - Si la dirección efectiva de un operando de memoria está fuera del límite de segmento CS, DS, ES, FS o GS. La macro CLEAR_CPU_BUFFERS ejecuta la instrucción VERW antes de regresar al espacio de usuario. Use el selector %cs para hacer referencia al operando VERW. Esto garantiza que VERW no genere #GP para un usuario arbitrario %ds.
