Local memory disclosure via Bluetooth SDP overread
Published Dec 3, 2024 · Updated Dec 3, 2024
Out-of-bounds read in Android 6, 6.0.1, 7, 7.1.1, 7.1.2, 8, and 8.1 allows local users to disclose memory via Bluetooth SDP. In sdp_copy_raw_data in the Bluetooth stack, a crafted response can make the copy length exceed the decoded list length or remaining response-buffer capacity, so memcpy reads past the supplied data. Exploitation requires user interaction and no additional execution privileges; the bounded impact is disclosure of process memory rather than modification or service interruption.
