CVE-2025-22412
📋 TL;DR
This CVE describes a use-after-free vulnerability in Bluetooth SDP server code that allows remote code execution without user interaction. Attackers within Bluetooth range can exploit this to execute arbitrary code on affected devices. This affects Android devices with vulnerable Bluetooth implementations.
💻 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 malware, steal data, or maintain persistent access
Likely Case
Remote code execution leading to data theft, surveillance capabilities, or device control
If Mitigated
Limited impact if Bluetooth is disabled or devices are patched
🎯 Exploit Status
Exploitation requires Bluetooth proximity but no authentication or user interaction
🛠️ 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. Apply March 2025 Android Security Patch via Settings > System > System Update. 2. Reboot device after update completes. 3. Verify patch level in Settings > About phone > Android version.
🔧 Temporary Workarounds
Disable Bluetooth
androidTurn off Bluetooth when not in use to prevent exploitation
adb shell settings put global bluetooth_on 0
Settings > Connected devices > Connection preferences > Bluetooth > Toggle off
Restrict Bluetooth visibility
androidSet Bluetooth to non-discoverable mode to reduce attack surface
adb shell am start -a android.bluetooth.adapter.action.REQUEST_DISCOVERABLE
Settings > Connected devices > Connection preferences > Bluetooth > Device name > Turn off visibility
🧯 If You Can't Patch
- Disable Bluetooth completely when not actively pairing devices
- Implement network segmentation to isolate vulnerable devices from critical systems
🔍 How to Verify
