Esikhathini esingaphezudlwana kwesonto eledlule sishicilele i-athikili lapho sibike khona ukuthi iCanonical ibuyekeze i-Ubuntu kernel ukumboza amaphutha amaningi okuphepha. Bekunezimbungulu eziningi kunokuvamile kulolu hlobo lokuvuselelwa, kuvamile ukumboza cishe ama-4-5. Emahoreni ambalwa edlule, inkampani yethule enye Ukuvuselelwa kwe-Ubuntu kernel, kodwa kulokhu, nakuba kunconywa njalo ukwamukela izinguquko, akuphuthumi kangako.
Eqinisweni, kule mibiko emibili, abasebenzisi abaningi bakhathazeke ngomunye kuphela. Esokuqala yi- I-USN-5484-1, futhi ilungisa izimbungulu ezi-5 ezithinta Ubuntu 14.04. Siyakhumbula ukuthi le nguqulo ye-Ubuntu, eneminyaka engu-8 yokuphila, isesigabeni se-ESM, okungukuthi, ukusebenzisa ithuba lokusekelwa okunwetshiwe lapho amaphutha okuphepha e-kernel eqhubeka nokumbozwa. Omunye umbiko uthi I-USN-5485-1, futhi lena kufanele idonse ukunaka kwabasebenzisi abaningi be-Ubuntu, ngoba ithinta zonke izinguqulo ezisekelwayo, kufaka phakathi i-16.04 ne-14.04, leyo, njengoba sesishilo, esesigabeni se-ESM.
Ubuntu buhlanganisa izimbungulu ezintathu ezithinta zonke izinguqulo zabo
Izimbungulu ezintathu ezifakwe kulo mbiko wakamuva kanye nezincazelo zazo yilezi:
- 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 awazange enze ngokugcwele izenzo zokuhlanza kumabhafa wokugcwalisa ama-microarchitecture. Umhlaseli wasendaweni 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.
Ukuze uzivikele kuzo zonke lezi zinsongo, vele uqalise isikhungo sesofthiwe yokusabalalisa ngayinye bese ufaka amaphakheji amasha e-kernel. Angabuye afakwe ngokuvula i-terminal bese uthayipha igama elithi «ukuvuselelwa kwe-sudo apt && sudo apt ukuthuthukisa«. Nakuba kuzo zontathu lezi zimo kukhulunywa “ngomhlaseli wendawo”, kungcono ukuvikelwa, nokubuyekeza kubiza kancane.
