CVE-2025-32330

Auracast interception via low-entropy broadcast password

Published Sep 4, 2025 · Updated Sep 4, 2025

Information disclosure in Android 13 through 15 allows physically proximate attackers to intercept Auracast audio over Bluetooth. LocalBluetoothLeBroadcast.generateRandomPassword creates a 12-character hexadecimal key from two UUID segments, providing only 48 bits of random key material for Bluetooth LE Audio broadcast encryption. The weak key protects the stream, so an attacker within Bluetooth range can intercept its audio without user interaction or additional execution privileges.
