Dhowr toddobaad ka dib markii ugu dambeysay, Canonical ayaa dib u soo saartay cusboonaysiinta kernel si loo hagaajiyo dayacanka kala duwan. Munaasabaddan, dhammaanteen uma baahnid inaan walwalno, maadaama nidaamyada ay saameeyeen ay yihiin ruxruxii hore ee Ubuntu 16.04, hadda oo leh taageerada ESM, iyo noocii hore ee LTS ee Ubuntu, ie Focal Fossa ee la sii daayay Abriil 2020. Waana taas , kuwa doorbidaya inay ka boodaan nooca LTS oo ay u gudbaan nooca LTS, Ubuntu 22.04 uma muuqan doono cusbooneysiin ahaan Focal Fossa dhowr maalmood, oo ku beegan ISO 22.04.1.
Guuldarrooyinka laftooda, saddex warbixin ayaa la daabacay, USN-5500-1 kaas oo saameeya Ubuntu 16.04 ESM iyo USN-5485-2 y USN-5493-2 kaas oo saameeya Ubuntu 20.04. Waayo Focal Fossa wadarta 4 dayacan ayaa la hagaajiyay, halka Xenial Xerus, oo leh kala bar warbixinnada, uu helay 8 hagaajin. Laga soo bilaabo halkan, haddii aysan ahayn mid aad u dhib badan, waxaan ku talin lahaa in kor loogu qaado Bionic Beaver (18.04) ugu yaraan, maadaama ay sii wadi doonto in si buuxda loo taageero ilaa Abriil ee sanadka soo socda.
4 baylahdu waxay go'an tahay Ubuntu 20.04
Saldhigga adeegsadaha, waxa ugu xiisaha badan waa kutaannada lagu hagaajiyay Focal Fossa, waana kuwan soo socda:
- CVE-2022-21123- Waxaa la ogaaday in qaar ka mid ah soo-saareyaasha Intel aysan si buuxda u fulin ficillada nadiifinta ee kaydiyeyaasha la wadaago ee muhiimka ah. Weerarka deegaanka ayaa u isticmaali kara tan si uu u soo bandhigo macluumaadka xasaasiga ah.
- CVE-2022-21125- Waxaa la ogaaday in qaar ka mid ah soo-saareyaasha Intel aysan si buuxda u fulin ficillada nadiifinta ee kaydinta buuxinta microarchitecture. Weerarka deegaanka ayaa u isticmaali kara tan si uu u soo bandhigo macluumaadka xasaasiga ah.
- CVE-2022-21166- Waxaa la ogaaday in qaar ka mid ah soo-saareyaasha Intel aysan si sax ah u nadiifineynin inta lagu guda jiro hawlgallada gaarka ah ee qorista diiwaannada gaarka ah. Weerarka deegaanka ayaa tan u isticmaali kara si uu u muujiyo macluumaadka xasaasiga ah.
- CVE-2022-28388- Waxaa la ogaaday in hirgelinta 2-Device USB8CAN interface ee kernel Linux uusan si sax ah u maareynin xaaladaha khaladaadka qaarkood, taasoo horseedaysa laba-labo-la'aan. Weeraryahan maxalli ah ayaa tan u isticmaali kara in uu keeno diidmada adeegga (shilka nidaamka).
Iyadoo aan loo eegin nooca ama qaybinta la isticmaalo, iyo in kasta oo guuldarrooyinka badankoodu ay u baahan yihiin galaangal jireed oo qalab ah, waxaa muhiim ah in had iyo jeer la isticmaalo cusbooneysiinta la heli karo, ama ugu yaraan kuwa amniga ah. Xirmooyinka cusub ayaa hadda laga heli karaa Ubuntu 20.04 iyo 16.04.
