Masiku angapo apitawo, Point Perception, Israeli kuuma kwachinsinsi, anapeza chitetezo tsiku zero chitetezo ku Linux kernel amene amatha maselo osathambiri ma seva, PC ma PC, ndipo chofunika kwambiri, mafoni mafoni a Android mafoni . Wowononga ofuna kugwiritsa ntchito chiopsezo choterechi, akhoza kupeza maudindo apamwamba pa chipangizo ndipo angapeze mwayi wodalirika wopeza deta kapena kuchita ndondomeko malinga ndi chifuniro chake.
Zambiri zokhudza Linux Kernel Flaw
Malingana ndi akatswiri, chifukwa cha zolakwikazo chiri mu core Linux kernel , chomwecho ndi chimodzimodzi pa maseva, PC ndi Android zipangizo. Cholakwika ichi, chomwe chinapatsidwa dzina lakuti CVE-2016-0728, chikukhulupirira kuti chinakhudza oposa 60 peresenti ya zipangizo zonse za Android. Zodabwitsa, zolakwika izi zinayamba kuonekera mu 2012 mu Linux version 3.8 ndipo zidakalipo pa ma -32-bit ndi 64-bit Linux makazikidwe machitidwe.
Chokhumudwitsa apa n'chakuti chiopsezo chakhalapo kwa zaka pafupifupi zitatu ndipo chikhoza kulola osokoneza kuti athandizidwe mosavuta pa maselo a Linux-run, PC, Android ndi zipangizo zina. Amachokera ku kernel's keyring facility ndipo amalola mapulogalamu akuyenda pansi pa osuta kuti apange code mu kernel. Izi zikutanthauza kuti chiopsezo chikhoza kuyika zowonongeka za ogwiritsira ntchito, kuphatikizapo zowonjezera ndi zolembera, zomwe zingawonongeke.
Momwe zingakhalire Pose Choopsa kwa Android
Chinthu chomwe chikhoza kupangitsa chiopsezochi kukhala chodetsa nkhaŵa chachikulu ndi chakuti chimakhudza makoma onse, kuphatikizapo ARM. Izi zikutanthawuza, kuti zipangizo zonse za Android zogwiritsa ntchito Android 4.4 KitKat ndipo kenako, zimakhudzidwa nazo. Pakalipano, izi zimakhala pafupifupi 70 peresenti ya zipangizo zonse za Android.
Android OS idadziwika kale chifukwa cha kugawidwa kwake kwakukulu ndikusintha kuchedwa. Google imagawana mapepala oteteza ndi opanga zipangizo, omwe amawagwiritsa ntchito padera. Kampaniyo imapereka zosintha zina pogwirizana ndi othandizira ogwira ntchito . Kuti mupitirize kulimbikitsa nkhani, zambiri mwa zipangizozi zimalandira mapulogalamu a mapulogalamu okha kwa miyezi 18, pambuyo pake salandira zina zowonjezera kapena zolemba. Izi zikutanthauza kuti ambiri ogwiritsa ntchito chipangizo, makamaka omwe amagwiritsa ntchito zipangizo zakale za Android, sangathe kupeza zatsopano ndi zosintha zakusokoneza.
Chochitika ichi chimawoneka kuti chikuwonetsa kwa ogwiritsa ntchito kuti machitidwe akale a Android sakanakhalanso otetezeka kuti agwiritsidwe ntchito ndipo kuti nthawi zonse azikhala akukonzekera maluso awo kuti awone zinthu zatsopano zotetezera ndi zina. Iwenso ingakhale yankho lovuta ku vutolo - osati aliyense amene angakonde kusintha ma smartphone kapena piritsi kamodzi pazaka zingapo.
Pakadali pano, mafakitale a mafoni akhala akudziwika ndi mitundu yosiyanasiyana ya pulogalamu ya pulogalamu yaumbanda imene yakhala yosadziwika bwino. Pakadali pano, palibe vuto lina lomwe likuwonetsa ogwiritsa ntchito. Komabe, zenizenibe kuti Android ndichinthu chofewa cha pulogalamu ya pulogalamu yaumbanda ndipo ikhoza kungokhala nthawi yisanayambe winawake atayambitsa zovuta zowonongeka.
Linux ndi Google Plan Yomwe Iyenera Kuchita
Mwamwayi, ngakhale chiwopsezo chiripo, palibe vuto lina lomwe likuwonetsedwa. Komabe, akatswiri a chitetezo tsopano akukumba zakuya kuti apeze ngati cholakwika ichi chinagwiritsidwa ntchito nthawi ina m'mbuyomu. Magulu a chitetezo a Linux ndi Red Hat ayamba kale kugwira ntchito kuti apereke zizindikiro zofanana - ziyenera kupezeka pamapeto a sabata ino. Komabe, pali njira zina zomwe zingakhalebe zovuta, mwina kwa kanthawi.
Google siingapereke yankho lachangu komanso lodalirika ponena kuti vutoli lidzayendetsedwe bwanji m'munsi mwa Android code. Izi zamoyo, pokhala otseguka, zikhoza kukhala opanga zipangizo ndi opanga kuwonjezera ndikugawira chigamba kwa makasitomala awo. Pakadali pano, Google, monga nthawi zonse, idzapitiriza kutulutsa zosinthidwa mwezi ndi mwezi ndi makonzedwe a ziphuphu za Nexus line ya Android zipangizo. Chiphonachi chikukonzekera kuthandizira iliyonse ya zitsanzo zake kwa zaka zosachepera 2 pambuyo pa tsiku loyamba kugulitsa mu sitolo yake ya intaneti .
