CVE-2018-9449

Local information disclosure via unchecked SDP response length

Published Dec 3, 2024 · Updated Dec 3, 2024

Out-of-bounds read in Android 6 through 8.1 allows local users to disclose process memory through a malformed Bluetooth SDP response. The process_service_search_attr_rsp function in system/bt/stack/sdp/sdp_discovery.cc reads response fields without first verifying that the remaining PDU contains the requested bytes. A local malicious application needs no additional execution privileges or user interaction; exposure is limited to information disclosure from the Bluetooth process.
