Intel GPU draiveris (i915) tuvastati haavatavus (CVE-2022-4139), mis v\u00f5ib viia m\u00e4lu rikkumiseni v\u00f5i m\u00e4lu sisu lekitamiseni. Probleem ilmneb alates Linuxi kernelist 5.4 ja m\u00f5jutab 12. p\u00f5lvkonna Intel integreeritud ja diskreetseid GPU-sid, sealhulgas Tiger Lake, Rocket Lake, Alder Lake, DG1, Raptor Lake, DG2, Arctic Sound ja Meteor Lake. <\/p>\n
Probleem on p\u00f5hjustatud loogikaveast, mille t\u00f5ttu videodraiver ei l\u00e4htesta TLB pufferid GPU poolt m\u00f5nes riistvaras \u00f5igesti. Teatud juhtudel ei toimunud TLB l\u00e4htestamine \u00fcldse. Vale TLB puhverdamine v\u00f5ib v\u00f5imaldada protsessil GPU abil juurdep\u00e4\u00e4su f\u00fc\u00fcsilise m\u00e4lu lehtedele, mis ei kuulu sellele protsessile, mis v\u00f5ib v\u00f5imaldada teiste andmete lugemist v\u00f5i m\u00e4lu rikkumist muus protsessis. Praegu pole teada, kas haavatavust saab kasutada v\u00e4lja valitud m\u00e4lukohtade kahjustamiseks. \n Allikas: opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"
