Jasper Nuyens, grundl\u00e6ggeren af Linux Belgium, som har skabt et lag til brug af Linux i Tesla-bilernes informationssystem, foreslog en enkel m\u00e5de at reducere angrebsfladen p\u00e5 Linux-kernen for at mindske risikoen for kompromittering i lyset af en stigning i opdagelsen af farlige s\u00e5rbarheder ved hj\u00e6lp af AI. Da mange s\u00e5rbarheder typisk findes i specifikke kerne-moduler, der er tilg\u00e6ngelige for automatisk indl\u00e6sning, men som normalt ikke anvendes af de fleste brugere, foreslog Jasper at blokere un\u00f8dvendige moduler, der ikke anvendes i det aktuelle system eller generelt er sj\u00e6ldent brugt, som standard. <\/p>\n

Der er flere tusinde moduler tilg\u00e6ngelige i kernen, men de fleste systemer bruger kun et par hundrede, mens de resterende forbliver tilg\u00e6ngelige for indl\u00e6sning og potentielt kan indeholde s\u00e5rbarheder. Ideen er implementeret gennem skriptet ModuleJail, som bestemmer listen over moduler anvendt i det aktuelle system (gennem \/proc\/modules) og automatisk sorterer un\u00f8dvendige moduler ind i en sortliste. Skriptet er skrevet i shell, bruger almindelige systemv\u00e6rkt\u00f8jer (busybox er tilstr\u00e6kkeligt) og distribueres under GPLv3-licensen. <\/p>\n

Skriptet underst\u00f8tter udf\u00f8relse p\u00e5 Debian, Ubuntu, RHEL, Fedora, SUSE, AlmaLinux, Rocky Linux, Alpine og Arch Linux, og som resultat af sit arbejde genererer det filen \/etc\/modprobe.d\/modulejail-blacklist.conf, som almindeligvis bruges i systemet til at deaktivere automatisk indl\u00e6sning af kerne-moduler. Denne tilgang g\u00f8r det muligt at beskytte systemet preventivt uden at skulle indl\u00e6se specialiserede kerne-moduler eller k\u00f8re yderligere baggrundsprocesser til systemoverv\u00e5gning. <\/p>\n

Hvis n\u00f8dvendigt har brugeren mulighed for at tilf\u00f8je moduler til den hvide liste, som i \u00f8jeblikket ikke er indl\u00e6st, men som potentielt kan anvendes i arbejdet. Derudover er profiler, der tillader brugen af de mest n\u00f8dvendige moduler til typiske anvendelser af systemet, ogs\u00e5 tilg\u00e6ngelige for aktivering. Der tilbydes profiler som «minimal» (kun de vigtigste moduler og grundl\u00e6ggende FS), «conservative» (+ typiske drivere til servere og virtual machines<\/a>) og desktop (+ drivere til WiFi, Bluetooth, lyd og video).
