I GPU-driveren fra Intel (i915) er der opdaget en s\u00e5rbarhed (CVE-2022-4139), som kan f\u00f8re til hukommelsesskader eller datal\u00e6kager fra kernehukommelsen. Problemet opst\u00e5r fra Linux-kernen 5.4 og ber\u00f8rer b\u00e5de integrerede og diskrete GPU'er fra Intel 12. generation, herunder familierne Tiger Lake, Rocket Lake, Alder Lake, DG1, Raptor Lake, DG2, Arctic Sound og Meteor Lake. <\/p>\n
Problemet skyldes en logisk fejl, der f\u00e5r videodriveren til ukorrekt at nulstille TLB-buffere fra GPU'en p\u00e5 visse hardware. I visse tilf\u00e6lde blev TLB ikke nulstillet overhovedet. En ukorrekt nulstilling af TLB-buffere kan give mulighed for, at en proces kan tilg\u00e5 fysiske hukommelsessider, der ikke tilh\u00f8rer denne proces ved hj\u00e6lp af GPU'en, hvilket kan bruges til at l\u00e6se andres data eller beskadige hukommelsen i en fremmed proces. Det er endnu ikke bestemt, om s\u00e5rbarheden kan bruges til m\u00e5lrettet at beskadige hukommelsen p\u00e5 \u00f8nskede adresser. \u0412 \u0434\u0440\u0430\u0439\u0432\u0435\u0440\u0435 GPU Intel
