CVE-2025-22403Network attack vector

Remote code execution via freed SDP message logging

Published Aug 26, 2025 · Updated Aug 27, 2025

Use-after-free in Android 15 Bluetooth SDP allows remote attackers to execute arbitrary code through a crafted service-discovery exchange. After L2CA_DataWrite can free its message buffer, sdp_snd_service_search_req logs p_cmd->len from that released buffer instead of a locally derived length. Exploitation requires no authentication, additional execution privileges, or user interaction and compromises the affected Bluetooth service.
