Fix this by using signed subtraction. The call to\nmax() will correctly handle any negative numbers that are produced.\n\nApply the same fix to the other timings, even though those subtractions\nare less likely to underflow."},{"lang":"es","value":"En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/sun4i: dsi: Prevenir el subdesbordamiento al calcular el tamaño de los paquetes. Actualmente, la sobrecarga de paquetes se resta mediante aritmética sin signo. Con un pulso de sincronización corto, esto podría desbordarse y volver a la normalidad hasta cerca del valor máximo u16. Se soluciona mediante la resta con signo. La llamada a max() gestionará correctamente cualquier número negativo generado.
