💻 Affected Systems

Products:
  • Android devices with Bluetooth support
Versions: Android versions prior to March 2025 security patch
Operating Systems: Android
Default Config Vulnerable: ⚠️ Yes
Notes: Requires Bluetooth HFP support to be enabled, which is common in most Android devices with Bluetooth capabilities.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Full device compromise with attacker gaining complete control over the device, accessing sensitive data, installing malware, and using the device as a pivot point for further attacks.

🟠

Likely Case

Remote code execution leading to data theft, surveillance capabilities, or device enrollment in botnets.

🟢

If Mitigated

Limited impact with proper network segmentation, Bluetooth restrictions, and security monitoring in place.

🌐 Internet-Facing: LOW
🏢 Internal Only: HIGH

🎯 Exploit Status

Public PoC: ✅ No

Turn off Bluetooth completely when not in use

🧯 If You Can't Patch

  • Disable Bluetooth completely or restrict to trusted devices only
  • Implement network segmentation to isolate vulnerable devices from critical systems

🔍 How to Verify

Check if Vulnerable:

Check Android security patch level in Settings > About phone > Android version. If patch level is earlier than March 2025, device is vulnerable.

Check Version:

Settings > About phone > Android version

Verify Fix Applied:

Verify security patch level shows March 2025 or later in Settings > About phone > Android version.
