Intel yakasimbisa huchokwadi hweiyo UEFI firmware uye BIOS sosi makodhi akaburitswa nemunhu asingazivikanwe paGitHub. Huwandu hwe5.8 GB yekodhi, zvishandiso, zvinyorwa, mabhurobhu uye marongero ane chekuita nechizvarwa chefirmware yemasisitimu ane processors akavakirwa paAlder Lake microarchitecture, yakaburitswa muna Mbudzi 2021, yakaburitswa. Shanduko ichangoburwa kune yakaburitswa kodhi yaive yaSeptember 30, 2022.
Sekureva kwaIntel, kuvuza kwakaitika nekuda kwekukanganisa kwevechitatu, uye kwete nekuda kwekukanganisa kweiyo kambani. Zvinonzi zvakare kodhi yakaburitswa yakavharwa neProjekti Circuit Breaker chirongwa, chinopa mibairo kubva kumadhora mazana mashanu kusvika kumadhora zana ekuona matambudziko ekuchengetedza muIntel firmware uye zvigadzirwa (zvichireva kuti vaongorori vanogona kuwana mibairo yekutaura kusasimba kwakawanikwa vachishandisa zviri mukati meIntel firmware. kuvunza).
Hazvina kutaurwa kuti ndiani chaizvo akazove kwakabva kuvuza (Vagadziri vemidziyo yeOEM uye makambani ari kuvandudza tsika firmware akawana maturusi ekuunganidza firmware). Ongororo yezvirimo mudura rakabudiswa yakaratidza mamwe bvunzo nemasevhisi akanangana neLenovo zvigadzirwa ("Lenovo Feature Tag Test Ruzivo", "Lenovo String Service", "Lenovo Secure Suite", "Lenovo Cloud Service"), asi kubatanidzwa kwaLenovo mu kubuda kwacho hakusati kwasimbiswa. Iyo dura yakaratidzawo zvekushandisa uye maraibhurari ekambani Insyde Software, iyo inogadzira firmware yeOEMs, uye git log ine email kubva kune mumwe wevashandi veLC Future Center kambani, iyo inogadzira malaptops eOEM akasiyana. Makambani ese ari maviri anoshandira pamwe neLenovo.
Sekureva kweIntel, iyo kodhi inowanikwa pachena haina zvakavanzika data kana chero zvinhu zvinogona kubatsira mukuburitswa kwekusagadzikana kutsva. Panguva imwecheteyo, Mark Ermolov, uyo anonyanya kutsvakurudza nezvekuchengetedzwa kweIntel mapuratifomu, akaonekwa mune yakabudiswa archive ruzivo pamusoro pezvinyorwa zveMSR zvisina kunyorwa (Model Specific Registers, inoshandiswa, pakati pezvimwe zvinhu, kutarisira microcode, kutsvaga uye kugadzirisa), ruzivo pamusoro pe. izvo zviri pasi pechibvumirano chisina kuburitsa pachena. Uyezve, kiyi yakavanzika yakawanikwa mudura, yakashandiswa kusaina firmware, inogona kushandiswa kunzvenga Intel Boot Guard dziviriro (kushanda kwekiyi hakuna kusimbiswa; zvinogoneka kuti iyi kiyi yekuyedza).
