Kua tautuhia e Check Point he whakaraeraetanga i roto i te ALAC (Apple Lossless Audio Codec) nga kaiwhakawaehere oro oro i tukuna e MediaTek (CVE-2021-0674, CVE-2021-0675) me Qualcomm (CVE-2021-30351). Ko te raruraru ka taea te mahi i te waehere kaiwhai i te wa e tukatuka ana i nga raraunga whakahōputu motuhake ki te whakatakotoranga ALAC.
Ka nui haere te mōrearea o te ngoikoretanga nā te mea ka pā ki ngā taputapu e whakahaere ana i te tūāpapa. Android, he maramara MediaTek me Qualcomm. Nā te whakaekenga, ka taea e te kaiwhakaeke te whakahaere i te pūmanawa kino ki te taputapu, me te uru atu ki ngā raraunga whakawhitiwhiti kōrero me ngā raraunga rongorau a te kaiwhakamahi, tae atu ki ngā raraunga kāmera. E kiia ana e rua hautoru o ngā kaiwhakamahi waea atamai katoa e whakamahi ana i tēnei tūāpapa ka pāngia e tēnei raruraru. AndroidHei tauira, i te US, ko te tapeke o ngā waka katoa i hokona i te hauwhā tuawhā o te tau 2021 Android- ko ngā waea atamai i tukuna mai me ngā maramara MediaTek me Qualcomm i eke ki te 95.1% (48.1% - MediaTek, 47% - Qualcomm).
Kāore anō kia whakaaturia ngā taipitopito mō te whakamahinga o te ngoikoretanga, engari e ai ki ngā pūrongo ko ngā wāhanga o MediaTek me Qualcomm mō te tūāpapa Android I whakatikahia ngā hapa i te Hakihea 2021. I roto i te pūrongo ngoikoretanga o te tūāpapa o Hakihea Android Kua tautuhia ngā take hei ngoikoretanga nui i roto i ngā wāhanga motuhake mō ngā maramara Qualcomm. Kāore te ngoikoretanga i roto i ngā wāhanga MediaTek i whakahuatia i roto i ngā pūrongo.
He mea whakamere te whakaraerae na ona pakiaka. I te tau 2011, ka whakatuwherahia e Apple te waehere puna o te ALAC codec, e taea ai te kopiri o nga raraunga ororongo me te kore e ngaro te kounga, i raro i te raihana Apache 2.0, a ka taea te whakamahi i nga patent katoa e pa ana ki te kotēkē. I whakaputaina te waehere engari i waiho kia kore e tiakina, kaore ano kia whakarereketia mo nga tau 11 kua hipa. I te wa ano, i haere tonu a Apple ki te tautoko motuhake i te whakatinanatanga i whakamahia i roto i ona papaahi, tae atu ki te whakakore i nga hapa me nga whakaraeraetanga kei roto. Ko te MediaTek me te Qualcomm i ahu mai i o raatau whakatinanatanga ALAC codec i runga i te waehere puna tuwhera taketake a Apple, engari kaore i whakauruhia nga whakaraeraetanga i whakatutukihia i roto i te whakatinanatanga a Apple i o raatau papa.
Kaore ano he korero mo te whakaraerae i te waehere o etahi atu hua e whakamahi ana i te waehere ALAC tawhito. Hei tauira, kua tautokohia te whakatakotoranga ALAC mai i te FFmpeg 1.1, engari kei te kaha te pupuri i te waehere me te whakatinanatanga wetewaehere.
