Kuu alguses sai teadaolevaks uus kriitiline haavatavus Intel'i protsessorites, mida nimetatakse \u201eSpoiler\u201d. Probleemi tuvastanud spetsialistid teatasid, et AMD ja ARM protsessorid ei ole sellele vastuv\u00f5tlikud. N\u00fc\u00fcd on AMD ettev\u00f5te kinnitanud, et arhitektuuriliste omaduste t\u00f5ttu ei kujuta Spoiler ohtu nende protsessoritele.<\/p>\n

\"AMD<\/p>\n

Nagu Spectre ja Meltdown haavatavuste puhul, peitub uus probleem Intel'i protsessoritega seotud spekulatiivsete k\u00e4skude t\u00e4itmise mehhanismides. AMD kiipides on see mehhanism realiseeritud teisiti, sealhulgas kasutatakse teistsugust l\u00e4henemist operatsioonide haldamiseks m\u00e4lu ja vahem\u00e4lu osas. T\u00e4psemalt \u00f6eldes v\u00f5ib Spoiler saada juurdep\u00e4\u00e4su osalisele teabele aadressist (\u00fcle 11 aadressi bitti) laadimisoperatsioonide ajal. AMD protsessorid ei kasuta aadressi k\u00f5rgema kui 11 bitti osalisi vasteid laadimise konfliktide lahendamisel.<\/p>\n

\"AMD<\/p>\n

Oluline on m\u00e4rkida, et kuigi Spoiler, nagu ka Spectre, toetub spekulatiivse k\u00e4skude t\u00e4itmise mehhanismile, ei saa seda uut haavatavust sulgeda olemasolevate \u201eplaasterdamiste\u201d abil varasemate eksploitide vastu. See t\u00e4hendab, et aktuaalsed Intel'i protsessorid vajavad uusi plaastrit, mis v\u00f5ivad j\u00e4lle m\u00f5jutada kiipide j\u00f5udlust. Edasi liikudes on Intel'ilt kindlasti vajalikud arhitektuuri taseme parandused. AMD-l ei ole selliseid meetmeid vaja rakendada.<\/p>\n

\"AMD<\/p>\n

L\u00f5petuseks tasub m\u00e4rkida, et Spoiler m\u00f5jutab k\u00f5iki Intel'i protsessoreid, alates esimese p\u00f5lvkonna Core kiipidest kuni praeguste Coffee Lake Refresh'i mudelite ja veel turule mitte j\u00f5udnud Cascade Lake'i ning Ice Lake'i mudeliteni. Kuigi Intel'i probleemist teavitati juba eelmise aasta detsembri alguses ja alates Spoiler'i avalikustamisest on m\u00f6\u00f6dunud juba \u00fcle k\u00fcmne p\u00e4eva, ei ole Intel pakkunud mingeid v\u00f5imalikke lahendusi ega teinud ametlikku avaldust selle kohta.<\/p>\n
