Avaldatud on uuringu tulemused Linuxi tuuma vigade tuvastamise ja k\u00f5rvaldamise aja kohta. Andmed saadi 125 000 veast, mis on m\u00e4rgistatud Git-i hoidlas silti «Fixes:», viidates commit'ile, kus viga tekkis. Keskmine vea tuvastamise aeg tuumas oli 2,1 aastat. Kui arvesse v\u00f5tta vaid 2025. aastal parandatud vigu, oli see n\u00e4itaja 2,8 aastat. <\/p>\n

30% vigadest k\u00f5rvaldasid samad arendajad, kes need tekitavad. 56,9% vigadest k\u00f5rvaldatakse aasta jooksul. 13,5% vigadest j\u00e4i m\u00e4rkamata rohkem kui 5 aastaks (kui arvestada vaid 2025. aastal parandatud vigu \u2014 19,4%). Eba\u00fchtlase jaotuse t\u00f5ttu oli vigade mediaan olemasolu aeg tuumas 8 kuud 2005. aasta valimi jaoks ja 1 aasta 2025. aastal parandatud vigade jaoks. K\u00f5ige kauem olemas olnud viga tuumas oli puhver\u00fclekande \u00fcletamine ethtool'is, mis k\u00f5rvaldati 20,7 aasta p\u00e4rast.

\"Linuxi<\/center> <\/p>\n

Vigade tuvastamise d\u00fcnaamika erineb m\u00e4rkimisv\u00e4\u00e4rselt keskmisest m\u00f5nedes alam s\u00fcsteemides, n\u00e4iteks CAN bussij\u00f5u draiveris ja SCTP stackis kulub probleemide tuvastamiseks keskmiselt umbes 4 aastat, IPv4 stackis \u2014 3,6 aastat, USB ja TTY \u2014 3,5, Netfilter ja v\u00f5rgu stack \u2014 2,9, VM \u2014 1,8, GPU \u2014 1,4, BPF \u2014 1,1 aastat.

\"Linuxi<\/center> <\/p>\n

Tuvastamise aeg korreleerub vigade t\u00fc\u00fcpidega: keskmine tuvastamise aeg race condition'ite (seisundite) vigade puhul oli 5,1 aastat, t\u00e4isarvude \u00fclet\u00e4itumise puhul \u2014 3,9, juba vabastatud m\u00e4lu kasutamise puhul \u2014 3,2, puhver\u00fclekande ja m\u00e4lu lekkimise puhul \u2014 3,1, viidete loendamise puhul \u2014 2,8, nulln\u00e4idiku dereferentseerimise ja \u00fcksteise blokeerimise puhul \u2014 2,2 aastat. <\/p>\n

Saadud statistikas on samuti n\u00e4ha uute vigade automaatse otsimise, staatilise anal\u00fc\u00fcsi ja koodi testimise t\u00f6\u00f6riistade, nagu Syzkaller, KASAN, KMSAN ja KCSAN, rakendamise m\u00f5ju. N\u00e4iteks 2010. aastal ei olnud aasta jooksul registreeritud vigade parandusi. 2014. aastal tuvastati aasta jooksul 31% vigadest, 2018. aastal \u2014 54%, ja 2022. aastal \u2014 69% vigadest. <\/p>\n

Saadud statistikat kasutati masin\u00f5ppemudeli VulnBERT loomisel, mis ennustab haavatavuste olemasolu commit'ides. 2024. aasta commit'ide testimisel oli vea avastamise t\u00e4psus 92,2% valeh\u00e4irete m\u00e4\u00e4raga 1,2% (v\u00f5rdluseks varasem kergesti k\u00e4tte saadav mudel CodeBERT tuvastas 89,2% probleemidest valeh\u00e4irete tasemega 48,1%).
