Ngemuva kokubuyekeza i-Linux kernel ku-Ubuntu 20.10 nazo zonke izinhlobo ezisekelwa njengamanje ze-Ubuntu, iCanonical ikhiphe inguqulo ebuyekeziwe yephakeji Intel microcode ukubhekana nobuthakathaka bamuva obutholakala kumikhiqizo ye-Intel. Futhi manje baya ... impela sengivele ngilahlekelwe ukubala kusukela ngeSpecter neMeltdown. Kusukela lapho, kube nezinkinga eziningi zokuphepha ezihambisana nenkampani yaseSanta Clara.
Ngaphezu kwe ubungozi I-CVE-2020-8694 esivele imakwe ezimgqeni ze-Linux zazo zonke izinhlobo ze-Ubuntu, le phakheji entsha ye-Intel Microcode nayo inezimagqabhagqabha ze-microcode ezilungisa ezinye ezinjenge-CVE-2020-8695, CVE-2020-8696, ne-CVE-2020 -8698 . Lezi zamuva zingavumela ukuhlaselwa kwendawo futhi ziveze imininingwane ebucayi.
Icala I-CVE-2020-8695, ubungozi obutholwe ngu-Andreas Kogler, Catherine Easdon, Claudio Canella, Daniel Grus, David Oswald, Michael Schwarz noMoritz Lipp, kusici se-RAPL (Intel Running Average Power Limit) se-Intel microprocessors ethile. Kulokhu kuvumele ukuhlaselwa kwesiteshi esiseceleni kusilinganiso sokusetshenziswa kwamandla.
Endabeni I-CVE-2020-8696 ne-CVE-2020-8698 zitholwe ngu-Ezra Caltum, uJoseph Nuzman, uNir Shildan, no-Ofir Joseff kwamanye ama-microprocessors e-Intel, okwenza izinsiza ezabiwe zihlukaniswe ngokungafanele noma imininingwane ebucayi isuswe ngaphambi kokugcinwa noma ukudluliswa.
I-Canonical isheshe yakhipha lezi zinguquko ezintsha ze-Intel's microcode (Intel Microcode 3.20201110.0) ku-Ubuntu 20.10, Ubuntu 20.04 LTS, Ubuntu 18.04 LTS, Ubuntu 16.04 LTS, naku-Ubuntu 14.04 ESM, nakuwo wonke ama-flavour abo. Yize kungenzeka ukuthi nazo zigcotshwe ku-Debian, SUSE, Red Hat, nakwamanye ama-distros avame ukuthola iziqeshana zokuphepha ezivamile.
Uyazi, uma une-chip ye-Intel ethinteke kulokhu kuba sengozini, qiniseka ukuthi wena thuthukisa uhlelo ukuze uvikeleke kula maphutha okuphepha ...
