Adjacent information disclosure via Bluetooth heap over-read
Published Oct 30, 2023 · Updated Aug 2, 2024
Out-of-bounds read in Google Android 14 Bluetooth allows physically proximate attackers to disclose process memory without user interaction. Google has not disclosed the affected Bluetooth function; the component reads beyond a heap-buffer boundary while processing attacker-controlled Bluetooth data. An unauthenticated attacker must be within Bluetooth range, and the documented consequence is memory disclosure rather than code execution or service interruption.
