Ngokomphandi wezokhuseleko, Injineli ePhakamileyo eGithub, kukho bug kwiLinux ezinokuvumela izixhobo ezisondeleyo kuthi ukuba zisebenzise imiqondiso yeWiFi ukubhloka okanye ukubekeka esichengeni izixhobo ezinobungozi. Isiphene sokhuseleko sikhona kumqhubi we-RTLWIFI, esetyenziselwa ukuxhasa iichips zeRealtek zeWiFi kwizixhobo ezisebenzisa iinkqubo zokusebenza kweLinux. Okubi nangaphezulu, akukho mfuneko yokuba senze nantoni na ngomsebenzisi onobubi ukuxhaphaza ubungozi, ukuhlangabezana nje neemfuno ezithile.
Ibug ibangela ukuba umthwalo ongaphezulu kwi-Linux kernel xa ikhompyuter ene-Realtek ye-WiFi chip ikuluhlu lwesixhobo esibi. Kwimeko yecala elungileyo, ukuxhaphaza kuya kubangela ukuba inkqubo yokusebenza iphazamise, kodwa inokuvumela umhlaseli ukuba alawule ngokupheleleyo ikhompyuter. Kwithiyori. Eyona nto ixhalabisayo kukuba isiphoso asilunganga okoko yafunyanwa ngo-2013, xa eyona kernel yayihlaziyiweyo yayiyiLinux 3.10.1.
Ibug ekhoyo kwiLinux ukusukela ngo-2013
I-bug ilandelwa phantsi kwegama le-CVE-2019-17666 kwaye, kwiminyaka emithandathu kamva, kunjalo uye waphakamisa Isiqwenga sokuyilungisa, ngoLwesithathu odlulileyo ukuba ichanekile. Kulindeleke oko Ipatch iya kubandakanywa kwi-kernel ye-Linux kwiintsuku ezimbalwa ezizayo, kodwa abayicacisanga ukuba oku kungathetha ukuba i-bug iyakulungiswa ngokwaziswa kwe Linux 5.4 Iya kwenzeka ngasekupheleni kukaNovemba okanye ekuqaleni kukaDisemba.
Kodwa ukuba nabani na ukhathazekile ngale mpazamo, ngekhe bayithathe ngokungathí sina ngesizathu esinye: UNico Waisman, umphandi wezokhuseleko, uthi akukafumani bungqina besigqibo apho kuxhatshazwa khona ukuphunyezwa kwekhowudi enobungozi, ngoko basathetha ngento ethile. Kwelinye icala, uWaisman uthi «ukungaphumeleli kunzima“Kungoko kufanelekile ukuyeka ngaphambi kokuba umntu afumane uqeqesho.
“Ndisasebenza efama, kwaye ngokuqinisekileyo… izakuthatha ixesha (ewe, ingangabinako ukwenzeka loo nto). Kwiphepha, kukugcwala okufunekayo ukuxhaphaza. Okona kubi, kukukhanyela inkonzo; Kwimeko elungileyo, ufumana iqokobhe. '
Zizixhobo kuphela ezine-Realtek chip ezichaphazelekayo
Ukuba sesichengeni kunokwenziwa kusebenze xa isixhobo esichaphazelekayo sikwi-radius Ukusuka kwisixhobo esibi, okoko i-WiFi ivuliwe, kwaye ayifuni kunxibelelwano kumsebenzisi wokugqibela, oko kukuthi, kuthi. Isixhobo esikhohlakeleyo sisebenzisa ubungozi ekusebenziseni amandla okonga amandla abizwa ngokuba yi "Isaziso sokuFihla" kubandakanya iWi-Fi ngqo, umgangatho ovumela izixhobo ezimbini ukunxibelelana ngeWiFi ngaphandle kwesidingo sokufikelela. Uhlaselo luya kusebenza ukuba ulwazi oluthe ngqo kumthengisi longezwe kwiibhikhoni ze-WiFi. Xa umatshini osengozini ewufumana, ubangela ukuba umthwalo ongaphezulu we-Linux kernel usebenze ngaphezulu.
Le bug ichaphazela kuphela izixhobo ezisebenzisayo Iinkqubo zokusebenza kweLinux kunye neRealtek chip xa iWiFi ivuliwe. Ukuba sisebenzisa i-chip yeWiFi evela komnye umenzi okanye icinyiwe, into ekufaneleyo ukuba siqhagamshela kuphela nge-Ethernet kwaye asinazo ezinye izixhobo zokunxibelelana nenethiwekhi enye, ngekhe bakwazi ukwenza impazamo kunye nokulayisha ngaphezulu.
Okwangoku, akukho mntu uvela kwiRealtek okanye kuGoogle oza nengxelo enokusenza siqiniseke (okanye sikhathazeke), ke abaziwa ubuzaza boqobo bokwehluleka. Ekuphela kwento eqinisekileyo kukuba iminyaka emithandathu lixesha elide lokuba sesichengeni seKernel kernel. Oko kunye nokuba iziphene ezikhuselekileyo ezinokuthi zixhatshazwe kude kufuneka ziqwalaselwe ngokukhawuleza, ukwenzela ukuba kungekudala kuya kubakho uhlobo olutsha lomqhubi weRealtek weLinux olungisa le mpazamo. Ngethemba kungekudala.
