CVE-2020-0473

Status: ModifiedMedium (4.6)—

In updateIncomingFileConfirmNotification of BluetoothOppNotification.java, there is a possible permissions bypass. This could lead to local escalation of privilege allowing an attacker with physical possession of the device to transfer files to it over Bluetooth, with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-11Android ID: A-160691486
