Nella versione del kernel Linux 5.3 sono state adottate<\/a><\/noindex> sono state apportate modifiche con l'aggiunta di protezioni aggiuntive per le chiamate ioctl relative al driver floppy, che \u00e8 stato contrassegnato come non pi\u00f9 supportato

Il driver \u00e8 considerato obsoleto, poich\u00e9 \u00e8 difficile trovare hardware funzionante per i suoi test: tutti i dispositivi di archiviazione esterni attuali utilizzano generalmente l'interfaccia USB. Tuttavia, la rimozione del driver dal kernel \u00e8 ostacolata dal fatto che i controller dei floppy disk vengono ancora emulati nei sistemi di virtualizzazione. Pertanto, il driver rimane ancora nel kernel, ma il suo funzionamento corretto non \u00e8 garantito.<\/p>\n

Da un lato, la vulnerabilit\u00e0 rimane attuale poich\u00e9 il driver floppy viene caricato automaticamente in presenza di un controller emulato appropriato nei sistemi di virtualizzazione (ad esempio, viene utilizzato per impostazione predefinita in QEMU), ma d'altro canto, per sfruttare il problema \u00e8 necessario che sia connessa un'immagine del disco floppy preparata da un attaccante.<\/p>\n
