Kwiveki nje emva ixesha langaphambili, ICanonical ikwenzile kwakhona. Kwiveki ephelileyo, inkampani eqhuba uMark Shuttleworth ihlaziya i-kernel yenkqubo yokusebenza eyiphuhlisayo yokujongana nokukodwa, kodwa eyona nto iphambili ekubekweni emngciphekweni. Kule veki, ukubala zonke iinkqubo zokusebenza, ine ihlaziyiwe Ubuntu kernel ukulungisa ii-bugs zizonke, kodwa akukho nanye kuzo eya kuqala ngokubaluleka, ezinye zishiyeke kuphela neelebheli eziphambili.
Njengesiqhelo, iCanonical ikhuphe iingxelo zokhuseleko xa Sele bezikhuphile iindawo ezilungisa ukuba semngciphekweni. Iingxelo zezi I-USN-4318-1, apho bathetha ngobuthathaka obuchaphazela Ubuntu 18.04 LTS Bionic Beaver kunye Ubuntu 16.04 LTS Xenial Xerus, the I-USN-4319-1, apho basixelela malunga nobuthathaka obukhoyo kwi-Ubuntu 19.10 Eoan Ermine kunye no-Ubuntu 18.04, kunye I-USN-4320-1, apho basixelela khona nge-bug ekhoyo kwi-Ubuntu 16.04 kunye no-Ubuntu 14.04 ESM Trusty Tahr.
Hlaziya i-kernel yakho ukulungisa ukuya kwi-4 yeziphene zokhuseleko
Inqanaba lobukrakra linikezelwa ngokuxhomekeka kubukho bokuxhaphaza ukuba sesichengeni kunye nomonakalo abanokuthi bawenze. Kuzo zonke iimeko, ukufikelela kwasekhaya kuyacelwa ukuba kuxhaphaze iziphene, ezona zimbi zezikhankanyiweyo kwingxelo ye-USN-4318-1, ezibini ezichaphazela iinguqulelo ezimbini zokugqibela ze-LTS Ubuntu kwaye kunokukhokelela ekwaleni inkonzo (DoS) okanye ubhengeza ulwazi olubuthathaka. Bonke ubungozi bunokusetyenziselwa ukuphazamisa inkqubo, bonke ekuhlaleni.
Ukuzikhusela kuzo zonke ezi bugs, vula nje iziko lesoftware kuhanjiso olusekwe ku-Ubuntu kwaye ufake ifayile Iiphakheji ezintsha esele zisilindile. Ukuze utshintsho luqale ukusebenza, kwaye njengalo lonke ixesha sihlaziya i-kernel, kuyakufuneka ukuba uqalise kwakhona inkqubo yokusebenza, ukuba nje asisebenzisi iPatch Patch.
