ICanonical yethule uhlelo lwe- inguqulo entsha ye-kernel ye-Ubuntu 18.04. Noma-ke, yilokho esingakufunda uma sifuna imininingwane ngeLinux 5.0.0-23.24, inguqulo efana nesibuyekezo esikhishwe izolo: ikhasi elisemthethweni le-Ubuntu ubeka ukuthi inguqulo ethintekile yiBionic Beaver, kepha isibuyekezo siyatholakala kwiDisco Dingo. Okucacayo ukuthi le nguqulo entsha ikhishelwe i-Ubuntu 18.04 LTS uma isebenzisa i-Linux 5.0.x.
Okucacayo futhi yilokho iziqeshana ezifakwe kule nguqulo ezilungisa: Amaphutha ayi-4 okuphepha ixazululwe ngoJulayi 23 ye-Ubuntu 19.04 esizoyifaka imininingwane ngezansi. Inguqulo entsha, esiyikhumbulayo nayo ivele ngeDisco Dingo, yiLinux 5.0.0-23.24 ~ 18.04.1 ye-Ubuntu 18.04 LTS neLinux 5.0.0-23.24 ye-Ubuntu 19.04. Lapha sikhumbula izimbungulu abazilungise ngesonto eledlule eDisco Dingo nayizolo eBionic Beaver.
I-kernel entsha ilungisa lezi zinambuzane ezi-4
- I-CVE-2019-11487: kwatholakala ukuthi ukuchichima kwenamba kwakukhona ku-kernel ye-Linux lapho kukhonjwa amakhasi, okuholela ezindabeni zokusebenziseka okungenzeka ngemuva kokukhishwa. Umhlaseli wendawo angasebenzisa lokhu ukudala ukwenqatshwa kwensizakalo (ukuvalwa okungalindelekile) noma enze ikhodi engafanele.
- I-CVE-2019-11599: UJann Horn uthole ukuthi isimo somjaho sikhona ku-kernel ye-Linux lapho kwenziwa izincithakalo zememori. Umhlaseli wendawo angasebenzisa lokhu ukudala ukwenqatshwa kwensizakalo (ukuphahlazeka kwesistimu) noma ukuveza imininingwane ebucayi.
- I-CVE-2019-11833: Ukuqaliswa kohlelo lwefayela le-ext4 ku-kernel ye-Linux kutholakale kungavali imemori kahle kwezinye izimo. Umhlaseli wendawo angasebenzisa lokhu ukudalula imininingwane ebucayi (inkumbulo ye-kernel).
- I-CVE-2019-11884: Kutholwe ukuthi ukuqaliswa kwe-Bluetooth Human Interface Device Protocol (HIDP) ku-Linux kernel akuqinisekisanga kahle ukuthi izintambo zinqanyulwe i-NULL ezimweni ezithile. Umhlaseli wendawo angasebenzisa lokhu ukudalula imininingwane ebucayi (inkumbulo ye-kernel).
I-Canonical incoma ukubuyekeza ngokushesha okukhulu, ikakhulukazi abasebenzisi be-Ubuntu 18.04. Ngokwami, angazi namanje ukuthi kungani besungule i- inguqulo entsha ye-Ubuntu 19.04 nokuthi akukabi khona okwamanje uhlu lwezindaba akusizi ukuphuma ekungabazeni Kunoma ikuphi futhi njengokujwayelekile, kufanelekile ukukubuyekeza njengamanje. Siyakhumbula ukuthi ama-patches ngeke asetshenziswe kuze kube yilapho siqala kabusha ikhompyutha.
