Abathuthukisi bephrojekthi ye-GrapheneOS, ethuthukisa imfoloko evikelekile ye-codebase ye-AOSP (Android Open Source Project), bahlonze ubungozi esitakini se-Bluetooth seplathifomu ye-Android 14, okungase kuholele ekusebenziseni ikhodi kude. Inkinga ibangelwa ukufinyelela endaweni yememori esivele ikhululiwe (ukusebenzisa ngemva kwamahhala) kukhodi yokucubungula umsindo edluliswa nge-Bluetooth LE.
Ubungozi buhlonziwe ngenxa yokuhlanganiswa kokuvikela okwengeziwe ocingweni oluqinile_lomalloc, kusetshenziswa isandiso se-ARMv8.5 MTE (MemTag, Memory Tagging Extension), esikuvumela ukuthi ubophe omaka emsebenzini ngamunye wokwabiwa kwenkumbulo futhi uhlele isheke ukuze lisetshenziswe ngendlela efanele. yezikhombisi zokuvimba ukuxhashazwa kobungozi obubangelwa ukufinyelela kumabhulokhi enkumbulo asevele ekhululiwe , ukuchichima kwebhafa, amakholi ngaphambi kokuqaliswa, nokusebenzisa ngaphandle komongo wamanje.
Iphutha belilokhu livela kusukela kusibuyekezo se-Android 14 QPR2 (i-Quarterly Platform Release), eshicilelwe ekuqaleni kukaMashi. Esisekelweni sekhodi esiyinhloko seplathifomu ye-Android 14, indlela ye-MTE iyatholakala njengenketho futhi ayikasetshenziswa ngokuzenzakalela, kodwa ku-GrapheneOS isivele inikwe amandla ukuze uthole ukuvikelwa okwengeziwe, okwenze kwaba nokwenzeka ukuhlonza iphutha ngemva kokubuyekeza I-Android 14 QPR2. Isiphazamisi sidale ukuphahlazeka lapho kusetshenziswa amahedfoni e-Bluetooth e-Samsung Galaxy Buds2 Pro ane-firmware evumela ukuvikelwa okusekelwe ku-MTE. Ukuhlaziywa kwesigameko kubonise ukuthi inkinga ihlobene nokufinyelela inkumbulo esivele ikhululiwe kusibambi se-Bluetooth LE, hhayi ukwehluleka ngenxa yokuhlanganiswa kwe-MTE.
Ukuba sengozini kulungisiwe ekukhishweni kwe-GrapheneOS okungu-2024030900 futhi kuthinta ukwakhiwa kwe-smartphone okungafaki ukuvikeleka okwengeziwe kwezingxenyekazi zekhompiyutha okusekelwe kusandiso se-MTE (i-MTE okwamanje inikwe amandla kuphela kumadivayisi we-Pixel 8 ne-Pixel 8 Pro). Ukuba sengozini kukhiqizwa kabusha kuma-smartphones e-Google Pixel 8 asebenzisa i-Android 14 QPR2. Kuma-smartphones ochungechunge lwe-Android ye-Pixel 8, imodi ye-MTE inganikwa amandla kuzilungiselelo zonjiniyela (“Izilungiselelo / Izinketho zesistimu / zikanjiniyela / Izandiso zokumaka inkumbulo”). Ukunika amandla i-MTE kukhulisa ukusetshenziswa kwenkumbulo cishe ngo-3%, kodwa akunciphisi ukusebenza.
