I GPU-driveret fr\u00e5 Intel (i915) er det oppdaget en s\u00e5rbarhet (CVE-2022-4139) som kan f\u00f8re til minneskader eller lekkasje av data fra kjerneminnet. Problemet oppst\u00e5r fra Linux-kjerne 5.4 og p\u00e5virker integrerte og diskrete GPUer fra Intel i 12. generasjon, inkludert familiene Tiger Lake, Rocket Lake, Alder Lake, DG1, Raptor Lake, DG2, Arctic Sound og Meteor Lake. <\/p>\n
Problemet er for\u00e5rsaket av en logisk feil som gj\u00f8r at videodriveren feilaktig tilbakestiller TLB-buffere fra GPU-siden p\u00e5 noe utstyr. I visse tilfeller skjedde det i det hele tatt ikke noen tilbakestilling av TLB. Feilaktig tilbakestilling av TLB-buffere kan f\u00f8re til at prosesser via GPU f\u00e5r tilgang til fysiske minnesider som ikke tilh\u00f8rer denne prosessen, noe som kan bli brukt til \u00e5 lese andres data eller skade minnet i en annen prosess. Det er fortsatt ikke fastsl\u00e5tt om s\u00e5rbarheten kan brukes til m\u00e5lrettet \u00e5 skade minnen p\u00e5 \u00f8nskede adresser. \u0412 \u0434\u0440\u0430\u0439\u0432\u0435\u0440\u0435 GPU
