Uma usebenzisa i-Ubuntu noma yikuphi ukunambitheka kwayo okusemthethweni, impela unesibuyekezo esisodwa noma eziningi ezisalindile. ICanonical ishicilele imibiko eminingi yezokuphepha ebala ubungozi obuhlukahlukene. Okwokuqala kwalokhu kuthinta ukwakheka okuncane kwe-Intel nama-GPU ahambisana nakho. Ngokuphelele, ukukhubazeka okungu-4 kulungiswe ku- Intel microcode: i-TSX Asynchronous Abort (I-CVE-2019-11135), Iphutha Lokuhlola Umshini We-Intel Processor (I-CVE-2018-12207) Futhi kwaziwa njenge-Intel i915 ihluzo zehardware yehardware (I-CVE-2019-0155 y I-CVE-2019-0154). Ukwehluleka okuthathu okungenhla kumakwe njengokubaluleke kakhulu.
Njengoba sifunda emibikweni I-USN-4182-1 y I-USN-4182-2, amasistimu wokusebenza athintwe yilobu bucayi ku-Intel Microcode yizo zonke izinhlobo ezisuselwe ku-Ubuntu ezijabulela ukwesekwa okusemthethweni ne-Ubuntu 14.04, kulokhu ngoba zisesigabeni se-ESM. Bonke abanye ubungozi ababulungisile sebevele bahlobene ikalishi ku-kernel Uhlelo lokusebenza lweCanonical.
Kulungiswe ukuba sengozini okubaluleke kakhulu okuthathu ku-Intel Microcode
Ngokuphathelene ne-kernel, iCanonical ishicilele imibiko yezokuphepha emi-4: the I-USN-4183-1 chaza Ukukhubazeka okungu-9 ku-Ubunutu kernel 19.10, the I-USN-4185-1 isitshela ngobungozi obungu-11 ku-Ubuntu 18.04 naku-Ubuntu 16.04, the I-USN-4186-1 ikwenza kube yi-12 ku-Ubuntu 16.04 kanye ne I-USN-4187-1 isho okunye ukuba sengozini ku-Ubuntu 14.04. Ubuthakathaka obuningi bukhona ezinhlotsheni ezahlukahlukene ze-Ubuntu futhi ngenkathi iningi libaluleke kakhulu, kukhona okunye okubaluleke kakhulu.
Njengenjwayelo, iCanonical ikhiphe imibiko yezokuphepha lapho Ukulungiswa kwamaphutha sekuyatholakala. Lokhu kusho ukuthi ukuzivikela kwizimbungulu ku-Intel Microcode nokunye ukukhubazeka ku-Ubuntu kernel, kufanele sivule isikhungo sethu se-software noma i-Software Update app bese sisebenzisa amaphakheji amasha asevele asilindile. Ukuze ushintsho luqale ukusebenza, ikhompyutha izodinga ukuqalwa phansi.
