Nakulokhu futhi, kufanele sikhulume ngakho amaphutha okuphepha kernel, kepha futhi siyabika lapho iCanonical isivele izilungisile. Sekukonke, ukutholakala kokukhubazeka okuthathu sekutholakele futhi sekuvele kumakiwe, enye yazo ifakwe ilebuli yi-Canonical njengokubaluleke kakhulu, kanti ezinye ezimbili zibhalwe njengeziphakathi nendawo. Konke ukuba sengozini kuthinta zonke izinhlobo ze-Ubuntu, kufaka phakathi Ubuntu 19.04, Ubuntu 18.04 LTS, ne-Ubuntu 16.04 LTS.
ICanonical ishicilele imibiko emibili ngalezi zinkinga ezintathu, the I-USN-4135-1 lapho besitshela khona ngezinhlobo ze-Ubuntu ezisakujabulela ukwesekwa okusemthethweni kanye ne- I-USN-4135-2 esikhuluma cishe ngento efanayo, kepha nge-Ubuntu 14.04 ne-Ubuntu 12.04 okwamanje eyi-ESM (Extended Security Maintenance) version. Akukanqunywa ukuthi iphutha elibi kakhulu kulaba abathathu lithinta Ubuntu 19.10 Eoan Ermine.
I-kernel entsha ilungisa lobu buthakathaka obuthathu
- I-CVE-2019-14835: kwatholakala i-buffer ichichima ekusetshenzisweni kwe-backend (vhost_net) kwenethiwekhi ye-virtio ku-Linux kernel. Umhlaseli esivakashini angasebenzisa lokhu ukudala ukwenqatshwa kwensiza (ukusingathwa kwe-OS) noma enze ikhodi engqubuzanayo ku-Host OS (okubaluleke kakhulu).
- I-CVE-2019-15030:eIKernel kernel ekwakhiweni kwePowerPC ayizange iphathe ngokwanele ukukhishwa kwesikhungo okungatholakali kwezinye izimo. Umhlaseli wendawo angasebenzisa lokhu ukudalula imininingwane ebucayi (okubaluleke kakhulu).
- I-CVE-2019-15031: i-kernel ye-Linux kubuciko be-PowerPC ayizange iphathe kahle okuhlukile kokuphazanyiswa kwezinye izimo. Umhlaseli wendawo angasebenzisa lokhu ukudalula imininingwane ebucayi
Ezixhumanisweni ezedlule, unalo lonke ulwazi mayelana namaphakeji okumele abuyekezwe, kepha ngokuyisisekelo kufanele sivule isibuyekezo sethu sesoftware futhi faka konke esikubona njenge- "linux-". Lapho wonke amaphakheji efakiwe, kufanele siqale kabusha ukuze izinguquko ziqale ukusebenza.
