Isticmaale kasta oo heerka dhexe ah ee Ubuntu wuu ogyahay inay sii daayaan nooc cusub oo nidaamkooda ku shaqeeya lixdii biloodba mar, in labadii sanaba mar uu jiro nooca LTS, iyo in kernel-ku uu qaadan karo waqti dheer in la cusbooneysiiyo. Dhab ahaantii, marka ay sameyso, waxay sidaas ku sameysaa noocyada LTS haddii aynaan raacin dhowr tillaabo sida kuwa ku jira maqaalkan ku saabsan sida loogu hayo Focal Fossa. Xaqiiqdu waxay tahay in kernel-ka la cusboonaysiiyay, laakiin lagu daro balastarrada amniga sidii ay u sameeyeen dhammaan noocyada Ubuntu kuwaas oo hadda la taageeray.
Dhowr saacadood ka hor, Canonical ayaa la daabacay saddex warbixin oo USN ah, gaar ahaan ah USN-5443-1, USN-5442-1 y USN-5444-1. Midka ugu horreeya wuxuu saameeyaa dhammaan noocyada Ubuntu ee wali la taageero, kuwaas oo ah Ubuntu 22.04 ee dhawaan la sii daayay, nooca kaliya ee aan LTS taageerno, kaas oo ah 21.10, ka dibna 18.04 iyo 16.04, oo hadda la taageeray sababtoo ah gelitaanka wejigeeda ESM , taas oo u oggolaanaysa inay sii socoto helitaanka balastarrada amniga.
Ubuntu waxay cusbooneysiisaa kernel-keeda amniga
Sharaxaadda USN-5443-1, waxaynu akhrinay laba guuldarro:
(1) Jadwalka isku xidhka kernel-ka Linux iyo nidaamka hoosaadka safka uma aysan samayn tirinta tixraaca si sax ah xaaladaha qaarkood, taasoo keentay baylahsanaan-la'aan isticmaalka ka dib. Weeraryahan maxalli ah ayaa u isticmaali kara tan si uu u keeno diidmada adeegga (habka shil) ama u fuliyo kood aan sabab lahayn. (2) Kernel-ka Linux si sax ah uma dhaqan gelin xannibaadaha seccomp xaaladaha qaarkood. Weeraryahan maxalli ah ayaa tan u isticmaali kara si uu uga gudbo xannibaadaha sanduuqa-cirifka ee seccomp loogu talagalay.
Ku saabsan USN-5442-1, kaas oo saameeya kaliya 20.04 iyo 18.04, saddex cayayaanka kale:
(1) Nidaam hoosaadka Jadwalka Shabakadda iyo Jadwalka hoose ee kernel-ka Linux si sax ah uma samayn tirinta tixraaca xaaladaha qaarkood, taasoo horseedaysa baylahsanaan-la'aan isticmaalka ka dib. Weeraryahan maxalli ah ayaa u isticmaali kara tan si uu u keeno diidmada adeegga (habka shil) ama u fuliyo kood aan sabab lahayn. (2)Nidaamka hoosaadka io_uring ee kernel-ka Linux waxa ku jira isugeyn xad dhaaf ah. Weeraryahan maxalli ah ayaa u isticmaali kara inuu keeno diidmada adeegga (shilka nidaamka) ama uu fuliyo kood aan sabab lahayn. (3) Kernel-ka Linux si sax ah uma dhaqan gelin xannibaadaha seccomp xaaladaha qaarkood. Weeraryahan maxalli ah ayaa tan u isticmaali kara si uu uga gudbo xannibaadaha sanduuqa-cirifka ee seccomp loogu talagalay.
Iyo ku saabsan USN-5444-1, kaas oo saameeya Ubuntu 22.04 iyo 20.04;
Isku-xidhka Shabakadda iyo Nidaam-hoosaadka Jadwalka ee kernel-ka Linux si sax ah uma samayn tirinta tixraaca xaaladaha qaarkood, taasoo keentay baylahsanaan-la'aan isticmaalka-ka-dib. Weeraryahan maxalli ah ayaa u isticmaali kara tan si uu u keeno diidmada adeegga (habka shil) ama u fuliyo kood aan sabab lahayn.
Si looga fogaado dhibaatooyinkan oo dhan, waxa kaliya ee loo baahan yahay in la sameeyo waa in la cusboonaysiiyo kernel-ka, taasna waa la samayn karaa si toos ah ula cusboonaysiinta aaladda cusboonaysiinta dhadhan kasta oo rasmi ah ee Ubuntu. Mar labaad, xasuusnoow inay mudan tahay in nidaamka qalliinka had iyo jeer si wanaagsan loo cusboonaysiiyo, ugu yaraan oo leh dhejisyadii ugu dambeeyay ee amniga.
