Ngemva kwamasonto ambalwa isikhathi sokugcina, I-Canonical iphinde yakhipha isibuyekezo se-kernel ukuze kulungiswe ubungozi obuhlukahlukene. Kulesi senzakalo, akuthina sonke okudingeka sikhathazeke, njengoba amasistimu athintekile kuyi-rocker endala Ubuntu 16.04, njengamanje enokusekelwa kwe-ESM, kanye nenguqulo yangaphambilini ye-LTS ye-Ubuntu, okungukuthi i-Focal Fossa ekhishwe ngo-Ephreli 2020. Futhi yilokho , kulabo abancamela ukweqa besuka enguqulweni ye-LTS baye enguqulweni ye-LTS, Ubuntu 22.04 ngeke ivele njengesibuyekezo ku-Focal Fossa izinsuku ezimbalwa, ehambisana ne-ISO ye-22.04.1.
Ngokuqondene nokwehluleka ngokwabo, imibiko emithathu ishicilelwe, i I-USN-5500-1 ethinta Ubuntu 16.04 ESM kanye I-USN-5485-2 y I-USN-5493-2 ezithinta Ubuntu 20.04. Ngoba I-Focal Fossa isamba sobungozi obu-4 bulungisiwe, kuyilapho i-Xenial Xerus, enengxenye yemibiko, ithole ukulungiswa okungu-8. Kusukela lapha, uma kungeyona inkinga enkulu, ngingancoma ukuthi ngithuthukele ku-Bionic Beaver (18.04) okungenani, njengoba izoqhubeka nokusekelwa ngokugcwele kuze kube ngu-April wonyaka ozayo.
4 ubungozi obulungisiwe ku-Ubuntu 20.04
Ngokwesisekelo sabasebenzisi, okuthakazelisa kakhulu izimbungulu ezilungiswe ku-Focal Fossa, futhi yizi ezilandelayo:
- I-CVE-2022-21123- Kutholwe ukuthi amanye ama-Intel processors awenzanga ngokugcwele izenzo zokuhlanza kumabhafa abiwe abalulekile. Umhlaseli wasendaweni angasebenzisa lokhu ukuze adalule ulwazi olubucayi.
- I-CVE-2022-21125- Kutholwe ukuthi amanye ama-Intel processors awenzanga ngokugcwele izenzo zokuhlanza kumabhafa wokugcwalisa i-microarchitecture. Umhlaseli wendawo angasebenzisa lokhu ukuze adalule ulwazi olubucayi.
- I-CVE-2022-21166- Kutholwe ukuthi amanye ama-Intel processors abengenzi kahle ukuhlanza ngesikhathi sokubhala okuthile kumarejista akhethekile. Umhlaseli wasendaweni angasebenzisa lokhu ukuze adalule ulwazi olubucayi.
- I-CVE-2022-28388- Kutholwe ukuthi ukusetshenziswa kwesixhumi esibonakalayo se-2-Device USB8CAN ku-Linux kernel akuzange kuphathe kahle izimo ezithile zamaphutha, okuholela ekukhululekeni kabili. Umhlaseli wasendaweni angasebenzisa lokhu ukuze abangele ukunqatshelwa kwesevisi (ukuphahlazeka kwesistimu).
Ngaphandle kwenguqulo noma ukusatshalaliswa okusetshenzisiwe, futhi nakuba ukwehluleka okuningi kudinga ukufinyelela okungokoqobo kudivayisi, kubalulekile ukuthi uhlale usebenzisa izibuyekezo ezitholakalayo, noma okungenani lezo zokuphepha. Amaphakheji amasha manje ayatholakala kumakhosombe we-Ubuntu 20.04 kanye ne-16.04.
