CVE-2024-43770

Adjacent code execution via unchecked GATT payload size

Published Jan 21, 2025 · Updated Mar 18, 2025

An out-of-bounds write in Android 12 through 15 allows remote attackers to execute code through an adjacent Bluetooth GATT request. The gatts_process_find_info path accepts a zero payload size returned after a channel closes, then continues buffer processing and writes out of bounds. An attacker must be within Bluetooth range; no privileges or user interaction are required, and successful exploitation grants code execution in the System component.
