Intel tau lees paub qhov tseeb ntawm UEFI firmware thiab BIOS cov lej luam tawm los ntawm ib tus neeg tsis paub ntawm GitHub. Tag nrho ntawm 5.8 GB ntawm cov cai, kev siv hluav taws xob, cov ntaub ntawv, blobs thiab cov chaw muaj feem xyuam rau tiam ntawm firmware rau cov tshuab nrog cov txheej txheem raws li Alder Lake microarchitecture, tshaj tawm thaum Lub Kaum Ib Hlis 2021, tau luam tawm. Qhov kev hloov tshiab tshaj plaws rau tus lej luam tawm yog hnub tim 30 Lub Cuaj Hli, 2022.
Raws li Intel, qhov xau tau tshwm sim los ntawm kev ua txhaum ntawm lwm tus neeg sab nrauv, thiab tsis yog los ntawm kev cuam tshuam ntawm lub tuam txhab cov txheej txheem. Nws tseem tau hais tias cov cai xau tau them los ntawm Project Circuit Breaker program, uas muab khoom plig txij li $ 500 txog $ 100000 rau kev txheeb xyuas cov teeb meem kev nyab xeeb hauv Intel firmware thiab cov khoom lag luam (hais tias cov kws tshawb fawb tuaj yeem tau txais khoom plig rau kev tshaj tawm qhov tsis zoo uas pom tau siv cov ntsiab lus ntawm cov khoom siv. leak).
Nws tsis tau qhia meej tias leej twg yog tus los ntawm qhov xau (OEM cov chaw tsim khoom thiab cov tuam txhab tsim kev cai firmware tau nkag mus rau cov cuab yeej rau kev sib dhos firmware). Kev tshuaj xyuas ntawm cov ntsiab lus ntawm cov ntaub ntawv luam tawm tau qhia qee qhov kev sim thiab cov kev pabcuam tshwj xeeb rau Lenovo cov khoom ("Lenovo Feature Tag Test Information", "Lenovo String Service", "Lenovo Secure Suite", "Lenovo Cloud Service"), tab sis Lenovo txoj kev koom tes hauv qhov xau tseem tsis tau lees paub. Cov ntaub ntawv tseem tau nthuav tawm cov khoom siv hluav taws xob thiab cov tsev qiv ntawv ntawm lub tuam txhab Insyde Software, uas tsim kho firmware rau OEMs, thiab cov ntawv teev git muaj email los ntawm ib tus neeg ua haujlwm ntawm LC Future Center tuam txhab, uas tsim cov laptops rau ntau yam OEMs. Ob lub tuam txhab koom tes nrog Lenovo.
Raws li Intel, cov cai muaj nyob rau hauv pej xeem tsis muaj cov ntaub ntawv tsis pub lwm tus paub lossis ib qho khoom siv uas tuaj yeem pab txhawb rau kev nthuav tawm qhov tsis zoo tshiab. Nyob rau tib lub sijhawm, Mark Ermolov, uas tshwj xeeb hauv kev tshawb fawb txog kev ruaj ntseg ntawm Intel platforms, tau txheeb xyuas nyob rau hauv cov ntaub ntawv luam tawm cov ntaub ntawv hais txog MSR cov ntawv sau npe tsis muaj ntaub ntawv (Cov Ntawv Sau Npe Tshwj Xeeb, siv, thiab lwm yam, rau kev tswj hwm microcode, tracing thiab debugging), cov ntaub ntawv hais txog uas yog ua raws li daim ntawv cog lus tsis qhia tawm. Ntxiv mus, tus yuam sij ntiag tug tau pom nyob rau hauv cov ntaub ntawv khaws tseg, siv los kos npe digitally firmware, uas tuaj yeem siv los hla Intel Boot Guard kev tiv thaiv (qhov ua haujlwm ntawm tus yuam sij tsis tau lees paub; nws muaj peev xwm hais tias qhov no yog qhov yuam kev xeem).
