CVE-2025-48593Public exploit

Remote code execution via Bluetooth SDP use-after-free

Published Nov 18, 2025 · Updated Nov 18, 2025

Use-after-free in Android 13 through 16 Bluetooth code allows remote attackers to execute code over an adjacent Bluetooth connection. The bta_hf_client_cb_init function reinitializes an HF client control block without canceling an existing SDP search, allowing overlapping discovery callbacks to free a new p_disc_db while the SDP layer retains and later reads it. Exploitation requires Bluetooth proximity, prior pairing, and a device with the Hands-Free client profile enabled; the demonstrated public proof of concept crashes the Bluetooth process on an Android Automotive emulator.
