Della console testuale implementata nel kernel Linux fornito codice rimosso<\/a><\/noindex>, che consente lo scorrimento del testo all'indietro (CONFIG_VGACON_SOFT_SCROLLBACK). Il codice \u00e8 stato rimosso a causa della presenza di errori che nessuno ha potuto correggere a causa dell'assenza di un mantenitore che si occupasse dello sviluppo di vgacon.<\/p>\n

Durante l'estate \u00e8 stata identificata un \u00e8 stato risolto<\/a><\/noindex> vulnerabilit\u00e0 (CVE-2020-14331) che potrebbe portare a un overflow del buffer a causa dell'assenza di adeguati controlli sulla disponibilit\u00e0 di memoria nel buffer di scorrimento. La vulnerabilit\u00e0 ha attirato l'attenzione degli sviluppatori, che hanno organizzato test di fuzzing sul codice di vgacon in syzbot<\/a><\/noindex>.<\/p>\n

Controlli aggiuntivi hanno rivelato ulteriori problemi simili nel codice di vgacon, cos\u00ec come problemi nell'implementazione software dello scorrimento nel driver fbcon. Sfortunatamente, il codice problematico \u00e8 rimasto a lungo senza manutenzione, probabilmente perch\u00e9 gli sviluppatori hanno iniziato a utilizzare console grafiche e le console testuali sono state abbandonate (le persone continuano a utilizzare le console vgacon e fbcon, ma da decenni non sono pi\u00f9 l'interfaccia principale del kernel e funzionalit\u00e0 avanzate come lo scorrimento integrato nel driver (Shift+PageUp\/PageDown) sono probabilmente poco richieste). <\/p>\n

Di conseguenza, Linus Torvalds ha deciso di non tentare di mantenere codice non richiesto, ma semplicemente di rimuoverlo. Se ci saranno utenti che troveranno necessaria questa funzionalit\u00e0, il codice per supportare lo scorrimento nella console sar\u00e0 reintegrato nel kernel non appena sar\u00e0 trovato un mantenitore disposto a prendersene cura.<\/p>\n
