Kwiiveki ezimbalwa emva koko kwilixa elidlulile, ICanonical iphinde yakhupha uhlaziyo lwekernel ukulungisa ubuthathaka obahlukeneyo. Ngesi sihlandlo, asingabo bonke abafuna ukuba nexhala, njengoko iinkqubo ezichaphazelekayo ziyi-rocker endala Ubuntu 16.04, ngoku kunye nenkxaso ye-ESM, kunye nenguqulo yangaphambili ye-LTS ye-Ubuntu, oko kukuthi i-Focal Fossa ekhutshwe ngo-Aprili 2020. Kwaye loo nto , Kulabo bakhetha ukwenza i-jump kwi-LTS version ukuya kwi-LTS version, Ubuntu 22.04 ayiyi kubonakala njengohlaziyo kwi-Focal Fossa iintsuku ezimbalwa, ngokuhambelana ne-ISO ye-22.04.1.
Ngokubhekiselele kwiintsilelo ngokwazo, iingxelo ezintathu ziye zapapashwa, i I-USN-5500-1 echaphazela Ubuntu 16.04 ESM kunye I-USN-5485-2 y I-USN-5493-2 echaphazela Ubuntu 20.04. Kuba IFocal Fossa iyonke yobuthathaka obu-4 bulungisiwe, ngelixa i-Xenial Xerus, enesiqingatha seengxelo, ifumene ukulungiswa kwe-8. Ukusuka apha, ukuba akukho ngxaki kakhulu, ndincoma ukuphuculwa kwe-Bionic Beaver (18.04) ubuncinane, njengoko iya kuqhubeka ixhaswa ngokupheleleyo kude kube ngu-Epreli wonyaka ozayo.
4 ubuthathaka obuzinzileyo ku-Ubuntu 20.04
Kwisiseko somsebenzisi, eyona nto inomdla kakhulu ziimpazamo ezilungisiweyo kwiFocal Fossa, kwaye zezi zilandelayo:
- I-CVE-2022-21123-Kwafunyaniswa ukuba ezinye iiprosesa ze-Intel azizange zenze ngokupheleleyo izenzo zokucoca kwii-buffers ezabelwana ngazo ezininzi. Umhlaseli wasekuhlaleni unokusebenzisa oku ukubonisa ulwazi olubuthathaka.
- I-CVE-2022-21125-Kwafunyaniswa ukuba ezinye iiprosesa ze-Intel azizange zizenze ngokupheleleyo izenzo zokucoca kwi-microarchitecture yokugcwalisa i-buffers. Umhlaseli wasekuhlaleni unokusebenzisa oku ukubonisa ulwazi olubuthathaka.
- I-CVE-2022-21166-Kwafunyaniswa ukuba ezinye iiprosesa ze-Intel azenzi ngokuchanekileyo ukucoca ngexesha lemisebenzi ethile yokubhala kwiirejista ezikhethekileyo. Umhlaseli wasekuhlaleni unokusebenzisa oku ukubonisa ulwazi olubuthathaka.
- I-CVE-2022-28388- Kwafunyaniswa ukuba ukuphunyezwa kwe-2-Device USB8CAN interface kwi-Linux kernel ayizange iphathe ngokuchanekileyo iimeko ezithile zempazamo, ezikhokelela kwi-double-free. Umhlaseli wasekhaya unokusebenzisa oku ukwenza ukwaliwa kwenkonzo (ukuphazamiseka kwenkqubo).
Kungakhathaliseki ukuba yiyiphi inguqulelo okanye ukuhanjiswa okusetyenzisiweyo, kwaye nangona ukusilela okuninzi kufuna ukufikelela ngokomzimba kwisixhobo, kubalulekile ukuba uhlale usebenzisa uhlaziyo olukhoyo, okanye ubuncinci ukhuseleko. Iiphakheji ezintsha ngoku ziyafumaneka kwi-Ubuntu 20.04 kunye ne-16.04 yokugcina.
