El m\u00f3dulo UsbCoreDxe crea un b\u00fafer de trabajo para transacciones USB fuera de SMRAM. El c\u00f3digo que se utiliza puede estar dentro de SMM, lo que hace que el b\u00fafer de trabajo sea una entrada no confiable. El b\u00fafer puede resultar da\u00f1ado por las transferencias DMA. El c\u00f3digo SMM intenta sanitizar los punteros para garantizar que todos los punteros se refieran al b\u00fafer de trabajo, pero cuando no se encuentra un puntero en la lista de punteros para sanitizar la acci\u00f3n actual no se cancela, lo que genera un comportamiento indefinido.
