CVE-2022-20445Network attack vector

Remote memory disclosure via unchecked SDP response length

Published Nov 8, 2022 · Updated May 1, 2025

An out-of-bounds read in Android's Bluetooth SDP client in versions 10 through 13 allows remote attackers to disclose process memory. process_service_search_rsp in sdp_discovery.cc fails to reject a negative remaining-message length before reading service handles from the response buffer. An unauthenticated Bluetooth peer can trigger the read without user interaction; the documented consequence is memory disclosure only.
