El n\u00facleo de Linux 5.3 se han aceptado<\/a><\/noindex> incluye cambios que a\u00f1aden protecci\u00f3n adicional a las llamadas ioctl relacionadas con el controlador de disquetes, y el propio controlador se ha marcado como dejado sin soporte
\n(\"hu\u00e9rfano\"), lo que implica su cese de pruebas.<\/p>\n

El controlador se considera obsoleto, ya que es dif\u00edcil encontrar hardware operativo para sus pruebas: todos los dispositivos de almacenamiento externos actuales suelen usar interfaz USB. Adem\u00e1s, la eliminaci\u00f3n del controlador del n\u00facleo se ve obstaculizada por el hecho de que los controladores de disquetes todav\u00eda se emulan en sistemas de virtualizaci\u00f3n. Por lo tanto, el controlador se mantiene en el n\u00facleo, pero su correcto funcionamiento no est\u00e1 garantizado.<\/p>\n

Adem\u00e1s, en el controlador de disquetes se solucion\u00f3<\/a><\/noindex> vulnerabilidad<\/a><\/noindex> (CVE-2019-14283<\/a><\/noindex>), permite a un usuario no privilegiado, que tiene la capacidad de insertar su disquete, leer datos de \u00e1reas de memoria fuera de los l\u00edmites del b\u00fafer de copia (por ejemplo, en \u00e1reas adyacentes pueden contener datos residuales del cach\u00e9 del disco y del b\u00fafer de entrada). Por un lado, la vulnerabilidad sigue siendo relevante ya que el controlador de disquetes se carga autom\u00e1ticamente cuando hay un controlador emulado correspondiente en los sistemas de virtualizaci\u00f3n (por ejemplo, se utiliza por defecto en QEMU), pero por otro lado, para explotar el problema debe estar conectado una imagen de disquete preparada por un atacante.<\/p>\n
