CVE-2025-0093
📋 TL;DR
This vulnerability in Android's Bluetooth stack allows unauthorized access to Bluetooth bonding state information without proper permission checks. It affects Android devices with vulnerable Bluetooth implementations, potentially exposing sensitive device pairing information to nearby attackers. User interaction is required for exploitation, typically involving Bluetooth pairing attempts.
💻 Affected Systems
- Android devices with Bluetooth functionality

⚠️ Risk & Real-World Impact
Worst Case
Attackers could remotely enumerate all Bluetooth-paired devices, track device relationships, and potentially infer user behavior patterns or device usage habits without user knowledge.
Likely Case
Nearby attackers could gather information about Bluetooth device relationships and potentially identify specific device types or models paired with the target device.
If Mitigated
With proper network segmentation and Bluetooth security controls, impact is limited to information disclosure about Bluetooth pairing status only.
🎯 Exploit Status
Requires user interaction (pairing acceptance) and Bluetooth proximity; not a remote code execution vulnerability
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Android Security Patch Level March 2025 or later
Vendor Advisory: https://source.android.com/security/bulletin/2025-03-01
Restart Required: Yes
Instructions:
1. Check for Android system updates in Settings > System > System update. 2. Install March 2025 security patch or later. 3. Reboot device after installation. 4. Verify patch level in Settings > About phone > Android version > Security patch level.
🔧 Temporary Workarounds
Disable Bluetooth when not in use
androidTurn off Bluetooth functionality to prevent exploitation attempts
Settings > Connected devices > Connection preferences > Bluetooth > Toggle off
Restrict Bluetooth pairing
androidOnly pair with trusted devices and reject unknown pairing requests
🧯 If You Can't Patch
- Disable Bluetooth completely in device settings
- Implement physical security controls to limit Bluetooth range (e.g., Faraday cages for sensitive areas)
🔍 How to Verify
Check if Vulnerable:
Check Android security patch level: Settings > About phone > Android version > Security patch level. If earlier than March 2025, device is vulnerable.Check Version:
adb shell getprop ro.build.version.security_patchVerify Fix Applied:
Verify security patch level shows March 2025 or later. No specific Bluetooth bonding state information should be accessible without proper permissions.📡 Detection & Monitoring
Log Indicators:
- Unexpected Bluetooth pairing attempts from unknown devices
- Multiple failed pairing attempts
- Bluetooth bonding state changes without user interaction
