Mar labaad, waa inaan ka hadalno cilladaha amniga kernel, laakiin markale ayaan soo sheegaynaa markay Canonical horey u hagaajisay. Guud ahaan, seddex nuglaansho ayaa la helay oo horeyba loo dhajiyay, mid ka mid ah ayaa lagu calaamadeeyay Canonical inuu yahay mudnaan sare, halka labada kale loo calaamadeeyay inay yihiin mudnaan dhexdhexaad ah. Dhammaan seddexda nuglaansho waxay saameeyaan dhammaan noocyada Ubuntu, oo ay ku jiraan Ubuntu 19.04, Ubuntu 18.04 LTS, iyo Ubuntu 16.04 LTS.
Canonical ayaa daabacay laba warbixinood oo kusaabsan saddexda nuglaansho, USN-4135-1 taas oo ay nooga sheegaan noocyada Ubuntu ee wali ku raaxeysanaya taageerada rasmiga ah iyo USN-4135-2 taas oo si ficil ahaan ah u sheegaysa wax isku mid ah, laakiin Ubuntu 14.04 iyo Ubuntu 12.04 oo hadda ah nooca ESM (Extended Security Maintenance). Wali lama shaacin in cayayaanka ugu halista badan ee saddexda ah uu saameeyo Ubuntu 19.10 Eoan Ermine.
Qalabka cusub ayaa hagaajinaya seddexdan nugul
- CVE-2019-14835: waa la ogaaday kayd ka buuxsamaaya gadaal (vhost_net) hirgelinta shabakadda virio ee kernel-ka Linux. Weeraryahan martida ah ayaa tan u adeegsan kara inuu ku keeno diidmo adeeg (shilalka OS host) ama suurto gal ah inuu ku fuliyo koodh aan loo aabo yeelin OS martida loo yahay (mudnaanta sare).

Xidhiidhyadii hore, waxaad haysaa dhammaan macluumaadka ku saabsan xirmooyinka ay tahay in la cusbooneysiiyo, laakiin asal ahaan waa inaan furnaa barnaamijkeena cusbooneysiinta iyo Ku rakib wax kasta oo aan u aragno "linux-". Marka xirmooyinka oo dhan la rakibo, waa inaan dib u bilownaa si isbedeladu u dhaqan galaan.
