Ukuba usebenzisa Ubuntu okanye nayiphi na incasa yayo esemthethweni, ngokuqinisekileyo unayo enye okanye ezingaphezulu kokulindwayo kokuhlaziywa. ICanonical ipapashe iingxelo zokhuselo ezininzi ezidwelisa ubungozi. Eyokuqala kwezi ichaphazela ii-Intel's microarchitecture kunye nee-GPU ezinxulumene nazo. Lilonke, ukuba semngciphekweni kwe-4 kulungisiwe i-intel microcode: I-TSX yeAynchronous Abort (I-CVE-2019-11135), Impazamo yokujonga umatshini we-Intel (I-CVE-2018-12207) Kwaye yaziwa ngokuba yi-Intel i915 yemizobo yezixhobo zehardware (I-CVE-2019-0155 y I-CVE-2019-0154). Oku kusilela kungasentla kuphawulwe njengeyona nto iphambili ngokubaluleka.
Njengoko sifunda kwiingxelo I-USN-4182-1 y I-USN-4182-2, Iinkqubo zokusebenza ezichaphazeleka kolu buthathaka kwi-Intel Microcode zizo zonke iinguqulelo ezisekwe kwi-Ubuntu eyonwabela inkxaso esemthethweni kunye no-Ubuntu 14.04, kule meko kuba bakwisigaba se-ESM. Eminye yemingcipheko abaye bayilungisa sele inxulumene buggy kwi kernel Inkqubo yeCanonical.
Ukulungiswa kokuphakama okuphezulu okuphezulu kwi-Intel Microcode
Malunga nekernel, iCanonical ipapashe iingxelo zezokhuseleko ezi-4: the I-USN-4183-1 kuchaza 9 ukuba semngciphekweni kwi-Ubunutu kernel 19.10, i I-USN-4185-1 Isixelela malunga nokuchaphazeleka okungama-11 ku-Ubuntu 18.04 kunye no-Ubuntu 16.04 I-USN-4186-1 iyenza i-12 kwi-Ubuntu 16.04 kunye I-USN-4187-1 ikhankanya omnye umngcipheko ku-Ubuntu 14.04. Uninzi lwezinto ezisemngciphekweni ezikhoyo kwiinguqulelo ezahlukeneyo zoBuntu kwaye ngelixa uninzi zizezona ziphambili ngokuphakathi, kukho ezinye eziphambili.
Njengesiqhelo, iCanonical ikhuphe iingxelo zokhuseleko xa Ukulungiswa kwe-bug ngoku kuyafumaneka. Oku kuthetha ukuba ukuzikhusela kwiibgs kwi-Intel Microcode kunye nobunye ubungozi kwi-Ubuntu kernel, kufuneka sivule iziko lethu lesoftware okanye uHlaziyo lweSoftware kwaye sisebenzise iiphakeji ezintsha esele zisilindile. Ukuze utshintsho luqale ukusebenza, ikhompyuter iya kufuna ukuqalwa kwakhona.
