La \u00eenceputul acestei luni, a fost descoperit\u0103 o nou\u0103 vulnerabilitate critic\u0103 \u00een procesoarele Intel, numit\u0103 \u201eSpoiler\u201d. Speciali\u0219tii care au identificat problema au raportat c\u0103 procesoarele AMD \u0219i ARM nu sunt afectate de aceasta. Acum, compania AMD a confirmat c\u0103, datorit\u0103 caracteristicilor arhitecturale, Spoiler nu reprezint\u0103 o amenin\u021bare pentru procesoarele sale.<\/p>\n

\"AMD<\/p>\n

La fel ca \u0219i \u00een cazul vulnerabilit\u0103\u021bilor Spectre \u0219i Meltdown, noua problem\u0103 se afl\u0103 \u00een implementarea mecanismelor de execu\u021bie speculativ\u0103 a comenzilor \u00een procesoarele Intel. \u00cen cipurile AMD, acest mecanism este implementat diferit, utiliz\u00e2nd, \u00een special, o abordare diferit\u0103 \u00een gestionarea opera\u021biunilor din memoria opera\u021bional\u0103 \u0219i din cache. Mai exact, Spoiler poate accesa informa\u021bii par\u021biale despre adres\u0103 (peste 11 bi\u021bi din adres\u0103) \u00een timpul opera\u021biunilor de \u00eenc\u0103rcare. Iar procesoarele AMD nu utilizeaz\u0103 potriviri par\u021biale ale adreselor peste 11 bi\u021bi din adres\u0103 \u00een timpul rezolv\u0103rii conflictele de \u00eenc\u0103rcare.<\/p>\n

\"AMD<\/p>\n

Este important de men\u021bionat c\u0103, de\u0219i Spoiler, ca \u0219i Spectre, se bazeaz\u0103 pe mecanismul execu\u021biei speculative a comenzilor, nu se pot aplica \u201epatch-uri\u201d existente pentru a \u00eenchide noua vulnerabilitate, la fel cum s-a f\u0103cut \u00een trecut cu exploit-urile. Asta \u00eenseamn\u0103 c\u0103 procesoarele Intel actuale au nevoie de noi patch-uri, ceea ce ar putea afecta din nou performan\u021ba cipurilor. Pe viitor, Intel va necesita, desigur, solu\u021bii la nivel arhitectural. Compania AMD, pe de alt\u0103 parte, nu va trebui s\u0103 fac\u0103 astfel de demersuri.<\/p>\n

\"AMD<\/p>\n

\u00cen cele din urm\u0103, trebuie men\u021bionat c\u0103 Spoiler afecteaz\u0103 toate procesoarele Intel, \u00eencep\u00e2nd cu cipurile Core de prima genera\u021bie \u0219i continu\u00e2nd cu actualele Coffee Lake Refresh, precum \u0219i cu Cascade Lake \u0219i Ice Lake, care nu au fost \u00eenc\u0103 lansate. De\u0219i Intel a fost informat\u0103 despre problem\u0103 \u00eenc\u0103 de la \u00eenceputul lunii decembrie a anului trecut, iar de la publicarea informa\u021biei despre Spoiler au trecut deja mai bine de zece zile, compania Intel nu a prezentat nicio op\u021biune de solu\u021bionare a problemei \u0219i nici nu a oferit o declara\u021bie oficial\u0103 \u00een acest sens.<\/p>\n
