Kube yimva kwemini ethe cwaka kwilizwe leLinux, kodwa kwiiyure ezimbalwa ezidlulileyo ndabona ukuba kukho Uhlaziyo lwekernel kwaye ndandingaqinisekanga ukuba kutheni. Xa i-Canonical ihlaziya i-kernel yenkqubo yokusebenza kunye neencasa ezisemthethweni eziyixhasayo, bahlala bekwenza oko ukulungisa iimpazamo kwezokhuseleko, kodwa asinakuqiniseka de bayipapashe ingxelo malunga nayo. Le yinto esele bayenzile, i I-USN-4147-1 ukuba ngqo.
Into ebingalindelwanga ngumncedisi kukuba iinguqulelo ezintsha zekhava yekernel zinemingxunya emininzi. Iyonke, Ama-18 asengozini alungisiwe, uninzi lwazo luphantsi okanye alubalulekanga, kodwa zisixhenxe ezingxamisekileyo eziphakathi. Ubungqongqo ababunikeza kwezi ziphene zokhuseleko buxhomekeke kumonakalo abanokuthi bawenze kunye nokulula kokuwaxhaphaza. Ngesi sizathu, kukho ezinye zeebugs ezimiselweyo ezibhalwe njengeyona nto iphambili nangona ibug inokuxhatshazwa ngelixa ikufutshane nezixhobo ezihlaselweyo.
Ukuhlaziywa kwamagqabi e-kernel 7 emngciphekweni ophakathi ophakathi
Ubuthathaka abalungisileyo ichaphazela Ubuntu 19.04 kunye no-Ubuntu 18.04. Kwingxelo epapashiweyo abayikhankanyi enye inguqulelo ye-Ubuntu eyonwabela inkxaso yaseburhulumenteni, i-Xenial Xerus, okanye ezo zikwisigaba se-ESM, eziyi-Ubuntu 14.04 kunye ne-Ubuntu 12.04.
Kuzo zonke iibgs ezilungisiweyo, ndingagqamisa ezimbalwa ezinje nge I-CVE-2019-0136, apho umhlaseli angenza ukuba ikhompyuter yethu inqunyulwe kwinethiwekhi ye-Wi-Fi, okanye ezinye ezinje I-CVE-2019-13631 ethi, nangona beyithatha njengeyona nto iphambili, inokuba njalo ukuxhatshazwa ngokusondeleyo emzimbeni (ngaphandle kokufikelela ngokupheleleyo). Ezinye ezinokusetyenziswa ngendlela efanayo zezi I-CVE-2019-15117, i I-CVE-2019-15118, i I-CVE-2017-15212, i I-CVE-2019-15217, i I-CVE-2019-15218, i I-CVE-2019-15220, i I-CVE-2019-15221, i I-CVE-2019-15223, i I-CVE-2019-9506 okanye I-CVE-2019-15211. Zilishumi elinanye xa zizonke zezo zinokuxhatshazwa ngaphandle kokuba "zibambe" izixhobo.
Iinguqulelo ezintsha zekernel Sele zifumaneka kumaziko ahlukeneyo esoftware okanye i-Ubuntu yoHlelo lweSoftware kunye nazo zonke iincasa ezisemthethweni. Ukuze utshintsho luqale ukusebenza, kufuneka siqale kabusha ikhompyuter.
