Omwe akupanga pulojekiti ya GrapheneOS, yomwe ikupanga foloko yotetezeka ya codebase ya AOSP (Android Open Source Project), azindikira kuti pali chiwopsezo pagulu la Bluetooth papulatifomu ya Android 14, zomwe zitha kupangitsa kuti ma code akhazikitsidwe akutali. Vutoli limayamba chifukwa chofikira malo okumbukira omwe adamasulidwa kale (kugwiritsa ntchito-mfulu) mu code processing audio yomwe imafalitsidwa kudzera pa Bluetooth LE.
Chiwopsezocho chidadziwika chifukwa chophatikizira chitetezo chowonjezera mu hardened_malloc call, pogwiritsa ntchito kukulitsa kwa ARMv8.5 MTE (MemTag, Memory Tagging Extension), komwe kumakupatsani mwayi womanga ma tag ku ntchito iliyonse yogawa kukumbukira ndikukonzekera kuyang'ana kugwiritsa ntchito zolozera moyenera. kuletsa kugwiritsa ntchito ziwopsezo zomwe zimachitika chifukwa chofikira zomakumbukira zomasulidwa kale, kusefukira kwa buffer, kuyimba foni kusanayambike, ndikugwiritsa ntchito kunja kwa zomwe zikuchitika.
Cholakwikacho chakhala chikuwonekera kuyambira pomwe Android 14 QPR2 (Quarterly Platform Release) idasinthidwa koyambirira kwa Marichi. Pachiyambi chachikulu cha nsanja ya Android 14, makina a MTE alipo ngati njira ndipo sakugwiritsidwa ntchito mwachisawawa, koma mu GrapheneOS yathandizidwa kale kuti atetezedwe, zomwe zinapangitsa kuti athe kuzindikira cholakwikacho pambuyo pokonzanso Android 14 QPR2. Vutoli lidayambitsa ngozi mukamagwiritsa ntchito mahedifoni a Samsung Galaxy Buds2 Pro Bluetooth okhala ndi firmware yomwe idathandizira chitetezo chochokera ku MTE. Kuwunika kwa chochitikacho kunawonetsa kuti vutoli linali lokhudzana ndi kupeza kukumbukira komasulidwa kale mu Bluetooth LE handler, osati kulephera chifukwa cha kuphatikiza kwa MTE.
Chiwopsezochi chimakhazikika mu kutulutsidwa kwa GrapheneOS 2024030900 ndipo kumakhudza mapangidwe a foni yam'manja omwe samaphatikizapo chitetezo chowonjezera cha hardware kutengera kukulitsa kwa MTE (MTE pakadali pano ndiyongoyambitsa zida za Pixel 8 ndi Pixel 8 Pro). Chiwopsezochi chapangidwanso pa mafoni a Google Pixel 8 omwe ali ndi Android 14 QPR2. Pa mafoni a m'manja a Android a Pixel 8, mawonekedwe a MTE atha kuyatsidwa pazokonda zopanga ("Zikhazikiko / Dongosolo / Zosankha Zopanga / Zowonjezera Zakukumbukira"). Kuthandizira MTE kumawonjezera kugwiritsa ntchito kukumbukira pafupifupi 3%, koma sikuchepetsa magwiridwe antchito.
