Greg Kroah-Hartman, odgovoran za podr\u0161ku stabilnim i 'staging' granama Linux jezgra i glavni odr\u017eava\u010d u 16 podsystema jezgra, odr\u017eao je izlaganje na konferenciji Rust Week 2026, u kojem je govorio o tome kako Rust mo\u017ee pomo\u0107i u spre\u010davanju pojave ranjivosti unutar jezgra, koje nastaju usled uobi\u010dajenih gre\u0161aka programera na C jeziku prilikom rada sa memorijom, blokadama, obradom gre\u0161aka i radom sa nepouzdanim podacima. Kao glavna prednost Rust-a isti\u010de se mogu\u0107nost identifikacije takvih gre\u0161aka u fazi gradnje, a ne prilikom ljudske revizije koda. Ipak, Rust se ne gleda kao \u010darobno re\u0161enje koje bi moglo da re\u0161i sve probleme, niti se planira da se jezgro prepisuje na Rust: o\u010dekuje se postepena implementacija Rust-a kroz njegovo kori\u0161\u0107enje za nove drajvere i podsysteme.<\/p>\n

Kao primjer gre\u0161aka u jezgru koje bi se mogle izbje\u0107i kori\u0161tenjem Rust-a, spomenuta je gre\u0161ka u Bluetooth pod-sustavu koja je ostala neprimije\u0107ena 15 godina, uz problem u hipervizoru Xen. U prvom slu\u010daju, programer je izvr\u0161io dereferenciranje pokaziva\u010da bez provjere, dok je u drugom zaboravio otklju\u010dati blokadu u kodu za obradu gre\u0161aka.
\nPrema Gregu, ve\u0107ina gre\u0161aka u jezgru uzrokovana je sli\u010dnim sitnicama koje se s vremenom nakupljaju i isplivavaju kao ranjivosti. U Rust-u, mnoge od ovih problema sprje\u010dava prevodilac; na primjer, Rust-ove apstrakcije za blokade u jezgru omogu\u0107uju pristup internim pokaziva\u010dima struktura tek nakon stjecanja odgovaraju\u0107e blokade, koja se automatski uklanja. Bez stjecanja blokade, pristup pokaziva\u010dima struktura u Rust-u nije mogu\u0107. <\/p>\n

Greg smatra da ovakve mogu\u0107nosti Rust-a ne bi dopustile pojavu 60% gre\u0161aka koje se otkrivaju u jezgru, a provjere koje provodi prevodilac oslobodile bi programere od tro\u0161enja vremena na rasprave s autorima o ispravnosti obrade gre\u0161aka i opravdanosti postavljanja blokada na pravim mjestima. \u0160tavi\u0161e, implementacija podr\u0161ke za Rust ve\u0107 je pozitivno utjecala i na C-kod u jezgru zahvaljuju\u0107i uvo\u0111enju reda u C-kod i interfejse, kao i preuzimanju nekih razvojnih pristupa (na primjer, implementirane su blokade s ograni\u010denim opsegom vidljivosti).<\/p>\n

Zahvaljuju\u0107i sistemu tipova koji osigurava pridr\u017eavanje zadatih pravila, kao i primjeni sistema kontinuirane integracije koji provjeravaju kod tokom kompilacije, prilikom recenziranja promjena u Rustu, recenzenti se mogu fokusirati na provjeru logike rada, a ne na pra\u0107enje manipulacija resursima. Primjena Rust-a tako\u0111er omogu\u0107ava pa\u017eljiviji pristup podacima koji dolaze sa opreme ili iz vanjskih sistema. Ovo se posti\u017ee jasnim razdvajanjem pouzdanih i nepouzdanih podataka na nivou sistema tipova: programeru je samo potrebno izvr\u0161iti analizu prilikom prelaska iz nepouzdanog u pouzdano stanje.<\/p>\n

U posljednje vrijeme tim koji se bavi sigurno\u0161\u0107u jezgra objavljuje otprilike 13 izvje\u0161taja o ranjivostima svaki dan, \u0161to se u odnosu na prethodnu dinamiku otkrivanja ranjivosti do\u017eivljava kao neka vrsta ludila (na primjer, ju\u010der je objavljeno 277 izvje\u0161taja o ranjivostima u jezgru). Po mi\u0161ljenju Grega, kori\u0161tenje Rust-a je jedan od stvarnih na\u010dina za smanjenje broja gre\u0161aka u jezgru, uzrokovanih tradicionalnim proma\u0161ajima u obradi gre\u0161aka i upravljanju resursima. U jezgru je podr\u0161ka za Rust ve\u0107 nadma\u0161ila eksperiment i krajem pro\u0161le godine je priznata kao standardna mogu\u0107nost jezgra. <\/p>\n
