I-kernel yeLinux iphuhliswa yiLinux Torvalds, kodwa emva koko iyayinyamekela ukuyigcina iyinxalenye yeqela labo. Akunjalo kunikezelo olufana noBuntu, kuba yi-Canonical ophetheyo ukugcina isiseko senkqubo yakho yokusebenza, ekhulula ukhuseleko kunye nohlaziyo lolondolozo amaxesha ngamaxesha, kwilixa elidlulile ngomhla weshumi elinesixhenxe kule nyanga. Bayenzile kwakhona kwiiyure ezimbalwa ezidlulileyo, besungula Iinguqulelo ezintsha zekernel kwiinguqulelo ezimbini zokugqibela zeBuntu.
Mhlawumbi, ukuba bekungenjalo umngcipheko ophambili Ngendingalibhalanga eli nqaku ndinika ingxelo ngokusilela. Kodwa i-bug eqokelelwa yingxelo I-USN-4313-1, inye kuphela, ewe ibhalwe ngale ndlela, ke ekugqibeleni ndigqibe kwelokuba ndabelana ngayo nani nonke. Ukuba sesichengeni yeyona nto I-CVE-2020-8835 kwaye, ekuqaleni, ichaphazela Ubuntu 19.10 Eoan Ermine kunye Ubuntu 18.04 LTS Bionic Beaver. Siyakhumbula apha ukuba Ubuntu 19.04 Disco Dingo ayisayonwabeli inkxaso.
Ukuhlaziywa kwekernel ukulungisa i-bug kwi-Eoan Ermine kunye neBionic Beaver
Igama okanye inkcazo yokuba semngciphekweni kukhankanyiwe "i-eBPF yokuQinisekiswa kokuNgena ngokuchanekileyo [i-ZDI-CAN-10780]", kwaye kwiinkcukacha zichaza ukuba:
UManfred Paul wafumanisa ukuba umhloli we-bpf kwi-Linux kernel akazange abale log umda kwimisebenzi ethile ngokuchanekileyo. Un Umhlaseli wendawo unokusebenzisa oku ukubonisa ulwazi olubuthathaka (inkumbulo yekernel) okanye ufumane amalungelo ezolawulo.
Ubungqongqo obabelweyo buxhomekeke ekukhululekeni kokuxhaphaza isiphako kunye nomonakalo onokubangela. Iindaba ezimnandi zezokuba ukuze usebenzise ubungozi, kufuneka ufikelele kwikhompyuter, ngamanye amagama kukwathetha ukuba Akukho mntu unokwenza nantoni na ukude. Ukongeza kwaye njengesiqhelo, i-Canonical ipapashe ulwazi emva kokupapasha iiphakeji ezintsha esele zilindele thina njengohlaziyo. Ukuze utshintsho luqale ukusebenza kwaye sikhuselwe ngokupheleleyo, kuyakufuneka uyiqale kwakhona ikhompyuter.
