El Ubuntu kernel Iphuhliswe nguLinus Torvalds kwaye igcinwe ngabantu obathembileyo. Kwelinye icala, iinkampani ezinjengeCanonical zinoxanduva lokugcina i-kernel yazo ngokukhupha uhlaziyo lokhuseleko. Ukugqibela kwabo ukuyenza ibingoFebruwari 19, xa balungisa ubuncinci iziphene ezingama-23 zokhuseleko (kunzima ukuzazi ngokuchanekileyo ngenxa yenani leengxelo ezahlukeneyo abazipapashayo). Izolo, inkampani eqhuba uMark Shuttleworth iyenzile kwakhona.
Ngeli thuba balungise iziphene zokhuselo ezili-11, ubuncinci. Ezo zili-11 linani lezinto ezisemngciphekweni esisigxina ezibonakala kwingxelo I-USN-4300-1, apho iibhugi ezichaphazela Ubuntu 19.10 kunye Ubuntu 18.04 LTS zichaziwe. ICanonical ikhuphe ezinye iingxelo ezi-4: I-USN-4301-1 Ukuchaza iibhugi eziyi-8 ezichaphazela Ubuntu 18.04 LTS, USN-4302-1 eneenkcukacha ze-9 bugs ezichaphazela Ubuntu 18.04 LTS kunye Ubuntu 16.04 LTS, i I-USN-4303-1 ekhankanya ibug echaphazela Ubuntu 16.04 LTS kunye I-USN-4303-2, efanayo nale ingentla, kodwa nge-14.04 ESM.
Hlaziya Ubuntu bakho kwaye uqalise kwakhona ukuzikhusela kubungozi obahlukeneyo
Ngokubanzi, kukho izilungiso zebug ichaphazele iinguqulelo zenkqubo yeCanonical ukusuka nge-14.04 ukuya kwi-19.10. Ungalibali ukuba ziinkqubo zokusebenza ezixhaswayo kuphela ezinokufumana olu hlaziyo, oluziinguqulelo ze-LTS ukusukela ngo-2014, nangona i-14.04 ikwisigaba soLondolozo loKhuseleko oluNgezelelweyo, kunye no-Eoan Ermine, ukukhutshwa okuza kuqhubeka ukuxhaswa kude kube nguJulayi walo nyaka. Ubuntu 12.04, okwangoku kwisigaba se-ESM, ayikhankanywanga kuyo nayiphi na ibug, kodwa iFocal Fossa, kwisigaba sophuhliso, ibonakala kwiinkcukacha zobunye ubungozi, njenge I-CVE-2019-3016. Ngayiphi na imeko, iFocal Fossa ayizukufikelela kuhlobo lwayo oluzinzileyo kude kube ngu-Epreli 23.
Iinguqulelo ezintsha zekernel ngoku ziyafumaneka njengombuyekezo kuzo zonke iinkqubo ezisebenzayo ezixhaswayo. Nje ukuba ifakwe, ikhompyuter kuya kufuneka iqaliswe kwakhona Utshintsho kufuneka luqale ukusebenza.
