Caangaarka Linux Kernel Developer iyo Maamulaha Greg Kroah-Hartman ayaa ku dhawaaqay dhamaadka wareegga nolosha ee Linux Kernel 4.20 taxanaha, isagoo ku boorriyay dadka isticmaala inay kor ugu qaadaan kernel cusub sida ugu dhakhsaha badan.
Waxaa la sii daayay Diisambar 23, 2018, taxanaha Linux Kernel 4.20 wuxuu la yimid tan oo hagaajin ah, oo ay ku jiraan hagaajinta Barxadda Siidaynta Laanta aan tooska ahayn (IBPB) iyadoo la adeegsanayo xakameynta hawsha, iyo yareynta weerarada la xiriira dayacanka Specter.
Intaa waxaa sii dheer, waxay soo bandhigtay difaac wanaagsan oo ka dhan ah u nuglaanta 'Specter variant 2' u nuglaanta, ilaalinta wanaagsan ee Specter variant 4 ee processor-yada ARM64 (AArch64), taageerida kaararka sawirada ee AMD Radeon Pro Vega, taageerada dhismaha naqshadaha C-SKY, iyo sidoo kale taageerada Hygon Dhyana x86 iyo AMD Radeon Picasso processor-yada iyo Kaararka sawirada Raven 2.
Laakiin maxaa yeelay wax walba oo wanaagsan waa inay dhammaadaan, Linux Kernel 4.20 wuxuu ku gaarayaa dhamaadka noloshiisa cusbooneysiintan ugu dambeysay, Linux Kernel 4.20.17, taas oo macnaheedu yahay inaanay jiri doonin wax cusbooneysiin ah taxanahan. Hadda qaybinta la doortay waa Linux Kernel 5.0.
U cusbooneysii Linux Kernel 5.0 hadda
Haddii aad u isticmaaleyso Linux 4.20 kernel taxane ah qaybintaada, hadda waxaa jira laba xulasho, u cusbooneysii nooca ugu dambeeyay, Linux Kernel 4.20.17 ama u cusbooneysii Linux Kernel 5.0. Haddii Linux Kernel 5.0 aan laga heli karin bakhaaradaada qaybinta, waxaa ugu wanaagsan in kor loogu qaado kernel taageero muddo dheer soconaya (LTS).
Taxanaha Linux Kernel ee leh taageerada LTS waxaa ka mid ah Linux 4.19 (lagu taliyay), Linux 4.14, Linux 4.9, Linux 4.4, iyo Linux 3.16. Laakiin Waxaan kugula talineynaa inaad u cusbooneysiiso Linux Kernel 5.0 sida ugu dhakhsaha badan.
