Na pocz\u0105tku tego miesi\u0105ca ujawniono now\u0105 krytyczn\u0105 luk\u0119 w procesorach Intel, nazwan\u0105 \u201eSpoiler\u201d. Specjali\u015bci, kt\u00f3rzy zidentyfikowali problem, poinformowali, \u017ce procesory AMD i ARM nie s\u0105 na ni\u0105 nara\u017cone. Teraz firma AMD potwierdzi\u0142a, \u017ce dzi\u0119ki cechom architektonicznym Spoiler nie stanowi zagro\u017cenia dla jej procesor\u00f3w.<\/p>\n

\"AMD<\/p>\n

Podobnie jak w przypadku luk Spectre i Meltdown, nowy problem tkwi w realizacji mechanizm\u00f3w spekulatywnego wykonania instrukcji w procesorach Intel. W chipach AMD mechanizm ten jest zrealizowany inaczej, w szczeg\u00f3lno\u015bci stosuje si\u0119 inny spos\u00f3b zarz\u0105dzania operacjami w pami\u0119ci operacyjnej i cache. M\u00f3wi\u0105c dok\u0142adniej, Spoiler mo\u017ce uzyska\u0107 dost\u0119p do cz\u0119\u015bciowych informacji o adresie (powy\u017cej 11 bitu adresu) podczas operacji \u0142adowania. Procesory AMD natomiast nie u\u017cywaj\u0105 cz\u0119\u015bciowych dopasowa\u0144 adres\u00f3w powy\u017cej 11 bitu adresu przy rozstrzyganiu konflikt\u00f3w \u0142adowania.<\/p>\n

\"AMD<\/p>\n

Warto zauwa\u017cy\u0107, \u017ce cho\u0107 Spoiler, podobnie jak Spectre, opiera si\u0119 na mechanizmie spekulatywnego wykonania instrukcji, zamkni\u0119cie nowej luki przy u\u017cyciu istniej\u0105cych \u201e\u0142at\u201d z wcze\u015bniejszych exploit\u00f3w jest niemo\u017cliwe. To znaczy, \u017ce aktualne procesory Intel potrzebuj\u0105 nowych poprawek, kt\u00f3re mog\u0105 ponownie wp\u0142yn\u0105\u0107 na wydajno\u015b\u0107 chip\u00f3w. A w przysz\u0142o\u015bci od Intel, oczywi\u015bcie, b\u0119d\u0105 wymagane poprawki na poziomie architektury. Firmie AMD nie b\u0119d\u0105 potrzebne podobne dzia\u0142ania.<\/p>\n

\"AMD<\/p>\n

Na koniec warto zauwa\u017cy\u0107, \u017ce Spoiler dotyczy wszystkich procesor\u00f3w Intel, pocz\u0105wszy od uk\u0142ad\u00f3w Core pierwszej generacji a\u017c po aktualne Coffee Lake Refresh, a tak\u017ce te, kt\u00f3re jeszcze si\u0119 nie pojawi\u0142y: Cascade Lake i Ice Lake. Pomimo \u017ce sama Intel zosta\u0142a powiadomiona o problemie ju\u017c na pocz\u0105tku grudnia zesz\u0142ego roku, a od momentu upublicznienia sprawy min\u0119\u0142o ju\u017c ponad dziesi\u0119\u0107 dni, firma Intel nie przedstawi\u0142a \u017cadnych mo\u017cliwych rozwi\u0105za\u0144 problemu ani nawet nie wyda\u0142a oficjalnego o\u015bwiadczenia w tej sprawie.<\/p>\n
