Se uye wafumanisa eyahlukileyo iSpecter variant (Variant 1) echaphazela ii-processor zale mihla ze-Intel kwaye mhlawumbi ezinye iiprosesa ze-AMD. UMicrosoft noRed Hat bebephethe uxanduva lokuphakamisa ialam, ukusukela oko IINTSHINTSHO sesichengeni esinokuvumela umhlaseli wendawo ongenalungelo ukuba afikelele kulwazi olunelungelo olugciniweyo kwimemori ye-kernel yenkqubo yokusebenza, kubandakanya amanye amagama okungena, iithokheni kunye nezitshixo zokubethela.
La ukwenziwa kwentelekelelo liyinxalenye esembindini yoyilo lwe-microprocessor yale mihla eyenza imiyalelo yokujonga ngokusekwe kucingelo oluthathwa njengenyaniso. Ukuba uqikelelo lusemthethweni, ukwenziwa kuyaqhubeka; kungenjalo ilahliwe. Ukuphunyezwa kokuqikelelwa ngolu hlobo kuneziphumo ebezingalindelekanga ezingabuyiswayo xa imeko ye-CPU ingalulanga, ekhokelela ekuvezweni kolwazi olunokuthi lufikeleleke ngokuhlaselwa ngamacandelo.
Abasebenzisi beLinux abasemngciphekweni omkhulu kwi-SWAPGS
Umyalelo we-SWAPGS yinkqubo yemfundo enelungelo lokutshintsha amaxabiso kwirejista ye-GS kunye nexabiso le-MSR kwaye ifumaneka kuphela kwizixhobo zokwakha ze-x86-64. Uhlaselo lwe-SWAPGS lwaphula itafile yekernel yodwa (i-KPTI) ebonelelwe zii-CPU zangoku kwaye inokusetyenziselwa ukucoca imemori ye-kernel ethe-ethe kwimo yomsebenzisi ongalambanga. Olu hlaselo lutsha luthintela zonke izinto ezincitshisiweyo ezenziweyo emva kokufunyanwa kweSpecter kunye neMeltdown. ekuqaleni kwe-2018 ebeka phantse yonke ikhompyuter emhlabeni emngciphekweni.
Ngaphandle kokukhulula nasiphi na isibhengezo esikhulu, uMicrosoft ukhuphe isiciko ukusikhusela kwi-SWAPGS kuhlaziyo lwayo lwangoJulayi 2019. UGoogle unendawo ayilungiselele iChannelOS yayo ezakukhupha kungekudala. Kwelinye icala, abasebenzisi beLinux bakhuselekile kancinci kuba, ngokutsho kwabaphandi bezokhuseleko, nangona i-kernel yeLinux ikwanento enokuthi isetyenziswe, ukuyenza kwi-linux kunzima ngakumbi kunakwinkqubo yeWindows.
Into elungileyo okanye ekufuneka isiqinisekise sonke yile ibug kufuneka ixhaphaze ekuhlaleni, ke asikho kuyo nayiphi na ingozi ukuba sivumela iqela lethu ukuba liyichukumise ngabantu abathembekileyo.
