NgoLwesibili olwedlule, iCanonical waphonsa izinhlobo ezintsha ze-kernel ze-Ubuntu 19.04 ne-Ubuntu 18.04. Yize ingxenye yalokho okwakhishelwa iBionic Beaver nayo yathunyelwa kuXenial Xerus, inguqulo ye-Ubuntu ekhishwe ngo-Ephreli 2016 yayingakayitholi inguqulo ethile, kuze kube namuhla: inkampani ephethe uMark Shuttleworth nayo ikhiphe Ukuvuselelwa kwe-kernel kwe-Ubuntu 16.04 ukulungisa amaphutha ayisithupha ephelele, elinye lawo lisuka ku-2018 futhi awekho amakhulu kakhulu.
Ngokungafani nezinguqulo ezikhishwe ngomhla wama-23, okukhishwe izolo kutholakala kuphela kubasebenzisi be-Ubuntu 16.04, ikakhulukazi labo basasebenzisa i-Linux 4.4 kernel. Abasebenzisi abathuthukisele enguqulweni yakamuva ye-Ubuntu noma i-kernel yayo abathinteki. Nakhu okuye kwalungiswa yinguqulo entsha.
Yini i-kernel elungisa isithombe se-linux 4.4.0-157.185
- I-CVE-2018-20836Isimo somjaho sitholakale sikhona ekusetshenzisweni kwe-Serial Attached SCSI (SAS) ku-kernel ye-Linux. Umhlaseli wendawo angasebenzisa lokhu ukudala ukwenqatshwa kwensizakalo (ukuphahlazeka) noma ukwenza ikhodi yokulamula. Okubaluleke kakhulu: okuphansi.
- I-CVE-2019-10142: Ukuchichima kwenamba kutholakale kumphathi we-Freescale hypervisor (PowerPC) ku-Linux kernel. Umhlaseli wendawo nge Ukubhala ukufinyelela ku / dev / fsl-hv kungakusebenzisa lokhu ukudala ukwenqatshwa kwensizakalo (crash) noma mhlawumbe usebenzise ikhodi yokulamula. Okubaluleke kakhulu: kuphansi kakhulu, kuncane.
- I-CVE-2019-11833: Kutholwe ukuthi ukuqaliswa kohlelo lwefayela le-ext4 ku-kernel ye-Linux ayizange ikhumbule kahle zero kwezinye izimo. Umhlaseli wendawo ungakusebenzisa lokhu ukudalula imininingwane ebucayi (inkumbulo ye-kernel). Okubalulekile okumaphakathi.
- I-CVE-2019-11884: Kutholakale ukuthi ukwenziwa kwe-Bluetooth HIDP (Isivumelwano Somuntu Sokusebenzelana Kwedivayisi) ku-kernel ye-Linux akuhlolisanga kahle imigqa lapho i-NULL iphele ezimeni ezithile. Umhlaseli wendawo angasebenzisa lokhu ukudalula imininingwane ebucayi (inkumbulo ye-kernel). Okubalulekile okumaphakathi.
- I-CVE-2019-9503: U-Hugues Anguelkov uthole ukuthi umshayeli we-Broadcom Wifi ku-kernel ayivimbelanga kahle imicimbi ye-firmware ekude ukuthi icubungulwe kumadivayisi we-USB WiFi. Umhlaseli oseduze angakusebenzisa lokhu ku- eThumela imicimbi ye-firmware kudivayisi. Okubalulekile okumaphakathi.
- I-CVE-2019-2054: I-Linux kernel kuma-processor we-ARM itholakele ukuvumela inqubo yokulandela umkhondo ukuguqula i-syscall ngemuva kwesinqumo se-seccomp esenziwe kulokho syscall. Umhlaseli wendawo angasebenzisa lokhu ukudlula imikhawulo yama-seccomp.
Uhlobo olusha lwe-kernel lwe-Xenial Xerus ngu isithombe se-linux 4.4.0-157.185. Njengenjwayelo, iCanonical ikhuthaza bonke abasebenzisi be-Ubuntu 16.04.x abane-Linux 4.4 ukubuyekeza ngokushesha okukhulu.
