W listopadowym biuletynie bezpiecze\u0144stwa Android opublikowano informacje o podatno\u015bci CVE-2025-48593 w podsystemie Bluetooth, kt\u00f3ra dotyczy wersji Android w przedziale od 13 do 16. Podatno\u015b\u0107 ta ma przypisan\u0105 krytyczn\u0105 ocen\u0119 ryzyka (9.8 na 10), poniewa\u017c mo\u017ce prowadzi\u0107 do zdalnego wykonania kodu w wyniku przetwarzania specjalnie przygotowanych pakiet\u00f3w Bluetooth. <\/p>\n

Firma Google na razie nie ujawnia szczeg\u00f3\u0142owego opisu podatno\u015bci, ale niezale\u017cni badacze twierdz\u0105, \u017ce problem nie dotyczy standardowych smartfon\u00f3w i odnosi si\u0119 jedynie do urz\u0105dze\u0144 Bluetooth, kt\u00f3re mog\u0105 dzia\u0142a\u0107 jako g\u0142o\u015bniki, takich jak inteligentne g\u0142o\u015bniki, inteligentne zegarki oraz systemy multimedialne w samochodach. Aby wykorzysta\u0107 luk\u0119, u\u017cytkownik musi sparowa\u0107 swoje urz\u0105dzenie z urz\u0105dzeniem atakuj\u0105cego, co oznacza, \u017ce wystarczy unika\u0107 akceptacji podejrzanych zaprosze\u0144 do sparowania (w biuletynie Google wspomniano, \u017ce do wykorzystania nie jest wymagane podejmowanie \u017cadnych dzia\u0142a\u0144 przez u\u017cytkownika). <\/p>\n

Poprawka polega na dodaniu wywo\u0142ania do sprawdzenia istnienia bazy danych Discovery podczas korzystania z profilu Bluetooth Handsfree oraz zatrzymaniu poszukiwania par z wykorzystaniem protoko\u0142u SDP (Service Discovery Protocol), a tak\u017ce zresetowaniu i oczyszczeniu struktury p_disc_db (\"baza danych odkry\u0107\"). Pewne manipulacje dotycz\u0105ce obs\u0142ugi b\u0142\u0119d\u00f3w i wznowienia po\u0142\u0105cze\u0144 w procesie ustalania us\u0142ugi Bluetooth oraz negocjacji interakcji. serwera<\/a> Zar\u00f3wno poprawka ju\u017c zosta\u0142a w\u0142\u0105czona do bazy kodowej LineageOS. Dost\u0119pny jest wczesny prototyp exploita, kt\u00f3ry powoduje awaryjne zamkni\u0119cie po uruchomieniu Androida w specjalnym emulatorze. W sieci r\u00f3wnie\u017c zauwa\u017cono pr\u00f3by sprzeda\u017cy dzia\u0142aj\u0105cego exploita, ale wydaje si\u0119, \u017ce s\u0105 to pr\u00f3by dystrybucji z\u0142o\u015bliwego oprogramowania lub sprzeda\u017cy oszustwa przez oszust\u00f3w. <\/p>\n

Poprawka ju\u017c zosta\u0142a w\u0142\u0105czona do bazy kodowej LineageOS.

Opr\u00f3cz tej luki, w listopadowej aktualizacji Androida zawarte jest poprawka dla luki CVE-2025-48581, prowadz\u0105cej do podwy\u017cszenia uprawnie\u0144. Problem dotyczy tylko Androida 16 i oznaczony jest jako niebezpieczny. Przyczyn\u0105 luki jest b\u0142\u0105d logiczny w funkcji VerifyNoOverlapInSessions z pliku apexd.cpp, kt\u00f3ry umo\u017cliwia blokowanie instalacji aktualizacji zawieraj\u0105cych poprawki bezpiecze\u0144stwa. Zauwa\u017cono, \u017ce luk\u0119 mo\u017cna wykorzysta\u0107 do lokalnego podwy\u017cszenia uprawnie\u0144. W celu przeprowadzenia ataku nie jest wymagane wykonywanie dzia\u0142a\u0144 przez u\u017cytkownika.
