CVE-2025-0074
📋 TL;DR
This critical vulnerability in Android's Bluetooth stack allows remote attackers to execute arbitrary code without user interaction or additional privileges. It affects Android devices with vulnerable Bluetooth implementations, potentially impacting billions of devices worldwide.
💻 Affected Systems
- Android devices with Bluetooth functionality
📦 What is this software?
Android by Google
⚠️ Risk & Real-World Impact
Worst Case
Complete device compromise allowing attacker to install persistent malware, steal sensitive data, and use device as pivot point in network attacks.
Likely Case
Remote code execution leading to data theft, surveillance capabilities, and device enrollment in botnets.
If Mitigated
Limited impact if Bluetooth is disabled or device is patched, though initial exploitation window remains critical.
🎯 Exploit Status
No user interaction required. Attacker needs to be within Bluetooth range (~10 meters).
🛠️ 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. 3. Reboot device. 4. Verify patch installation in Settings > About phone > Android version.
🔧 Temporary Workarounds
Disable Bluetooth
androidTurn off Bluetooth functionality to prevent exploitation
adb shell settings put global bluetooth_on 0
Or manually disable in Settings > Connected devices > Connection preferences > Bluetooth
Restrict Bluetooth visibility
androidSet device to non-discoverable mode to reduce attack surface
adb shell settings put global bluetooth_discoverability 0
🧯 If You Can't Patch
- Disable Bluetooth completely when not in active use
- 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 before 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. Check Bluetooth functionality remains operational.
