  • Android devices with Bluetooth functionality
Versions: Android versions prior to March 2025 security patch
Operating Systems: Android
Default Config Vulnerable: ⚠️ Yes
Notes: Requires Bluetooth to be enabled. All Android devices with vulnerable Bluetooth stack are affected.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Full device compromise with attacker gaining root/system-level access, enabling data theft, persistence, and further network attacks.

🟠

Likely Case

Local privilege escalation allowing attackers to bypass app sandboxing, access sensitive data, and install malware.

🟢

If Mitigated

Limited impact with proper security controls, but still poses risk to device integrity.

🌐 Internet-Facing: LOW - This is a local vulnerability requiring physical or network proximity to the device.
🏢 Internal Only: HIGH - Attackers on the same network or with physical access can exploit this without authentication.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ⚠️ Yes
Complexity: MEDIUM

No user interaction required. Exploitation requires sending specially crafted Bluetooth packets.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: March 2025 Android Security Patch or later

Vendor Advisory: https://source.android.com/security/bulletin/2025-03-01

Restart Required: Yes

Instructions:

1. Check for system updates in Settings > System > System update. 2. Install March 2025 security patch or later. 3. Reboot device after installation.

🔧 Temporary Workarounds

Disable Bluetooth

android

Turn off Bluetooth functionality to prevent exploitation

adb shell settings put global bluetooth_on 0
Settings > Connected devices > Connection preferences > Bluetooth > Turn off

🧯 If You Can't Patch

  • Restrict Bluetooth usage to trusted devices only
  • Implement network segmentation to isolate vulnerable devices

🔍 How to Verify

Check if Vulnerable:

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

Check Version:

adb shell getprop ro.build.version.security_patch

Verify Fix Applied:

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

📡 Detection & Monitoring

Log Indicators:

  • Bluetooth stack crashes in logcat
  • Unexpected Bluetooth service restarts
  • Privilege escalation attempts in system logs

Network Indicators:

  • Unusual Bluetooth packet patterns
  • Multiple connection attempts from single MAC address
  • Malformed Bluetooth protocol packets

SIEM Query:

source="android_logs" AND ("bluetooth" AND ("crash" OR "segfault" OR "use-after-free"))
