Local information disclosure via unchecked packet bounds
Published Mar 24, 2023 · Updated Feb 25, 2025
Out-of-bounds read in Google Android 13 Bluetooth audio allows local users to disclose process memory through crafted source packet data. GetNextSourceDataPacket in bta_av_co.cc reads beyond the available packet data because it omits a required bounds check. Exploitation requires local low-privileged access but no user interaction, and the reported consequence is limited to information disclosure.
