NixOS-i cryptsetup-suspend t\u00f6\u00f6riista portimise k\u00e4igus ilmus viga LUKS (Linux Unified Key Setup) ketta\u0161ifreerimise alams\u00fcsteemis, mille t\u00f5ttu alates Linuxi tuumast 6.9 (probleemne commit), mis ilmus 2024. aasta maikuus, ei toiminud \u0161ifreerimisv\u00f5tmete puhastamine RAM-ist, kui s\u00fcsteem l\u00e4ks ooteolekusse. <\/p>\n

Cryptsetup-suspend t\u00f6\u00f6riista kasutatakse Debiani s\u00fcsteemis automaatseks LUKS-osade lukustamiseks enne unere\u017eiimi sisenemist. Eeldatakse, et juhul, kui varastatud s\u00fclearvuti l\u00e4heb unere\u017eiimi, ei saa r\u00fcndaja juurde p\u00e4\u00e4seda andmetele, kuna unest v\u00e4ljumisel on vajalik sisestada parool, et taastada juurdep\u00e4\u00e4s kr\u00fcpteeritud andmetele. Linuxi kernelis esinenud vea t\u00f5ttu p\u00e4rast LUKS-osade lukustamist k\u00e4suga \u00abcryptsetup luksSuspend\u00bb ei kustutatud v\u00f5tmeid m\u00e4lust ja need olid n\u00e4htavad l\u00e4bi \/proc\/keys, mis v\u00f5imaldas r\u00fcndajal need v\u00e4lja v\u00f5tta n\u00e4iteks \u201ek\u00fclma taask\u00e4ivitamise\u201c meetodiga ja kasutada andmetele juurdep\u00e4\u00e4semiseks. <\/p>\n

V\u00f5tmete puhastamise puudumine tuvastati v\u00f5istlusseisundi silumise k\u00e4igus, mille t\u00f5ttu tekkisid probleemid uinakure\u017eiimi \u00fcleminekul. Viga ilmnes p\u00e4rast 6.9 p\u00f5hituuma refaktoreerimist, mille tulemusena siduti v\u00f5tmed v\u00e4ljakutsujate t\u00f6\u00f6r\u00fchmaga ja need pidid olema kustutatavad t\u00f6\u00f6 l\u00f5petamisel, kuid tegelikult j\u00e4id m\u00e4lu. <\/p>\n

See plaastrit ei ole tuuma vastu v\u00f5etud, kuna sellega on tuvastatud puudus \u2014 plaastrit rakendatakse ainult f\u00fc\u00fcsilistele andmekandjatele, kuid se ei toimi virtuaalsete loop-seadmete jaoks. Probleemi lahendamiseks ei pakutud tuuma arendajatelt parandust, vaid cryptsetup t\u00f6\u00f6riista arendajad pakkusid v\u00f5tmete kustutamiseks \u00fcmbers\u00f5itu. See muudatus on juba vastu v\u00f5etud ja lisatakse cryptsetup 2.8.7 v\u00e4ljaandesse. <\/p>\n

Lisaks sellele on NixOS-i jaoks loodud oma teostus skriptidest kr\u00fcpteeritud ketaste lukustamiseks enne uinakure\u017eiimi, milles kasutatakse 2015. aastal vastuv\u00f5tmata vanast pat\u0161ist tuumas, mis sunnib v\u00f5tmeid m\u00e4lu puhastama enne uinakure\u017eiimi sisenemist.
