CVE-2024-56189
📋 TL;DR
This vulnerability allows authenticated remote attackers to read memory beyond intended boundaries in SAEMM_RadioMessageCodec.c, potentially exposing sensitive information. It affects Android Pixel devices with the vulnerable SAEMM component. No user interaction is required for exploitation.
💻 Affected Systems
- Google Pixel devices
📦 What is this software?
Android by Google
⚠️ Risk & Real-World Impact
Worst Case
Remote information disclosure of sensitive memory contents including credentials, cryptographic keys, or other protected data from the device
Likely Case
Limited information leakage of adjacent memory structures, potentially exposing device identifiers or configuration data
If Mitigated
No impact if patched or if network segmentation prevents attacker access
🎯 Exploit Status
Requires authentication but no additional privileges, making it accessible to any authenticated user
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: April 2025 Android security patch or later
Vendor Advisory: https://source.android.com/security/bulletin/pixel/2025-04-01
Restart Required: No
Instructions:
1. Check for system updates in Settings > System > System update. 2. Install April 2025 security patch or later. 3. Verify patch installation in Settings > About phone > Android version.
🔧 Temporary Workarounds
Network segmentation
allRestrict network access to affected devices to prevent remote exploitation
Authentication hardening
allImplement strong authentication mechanisms and monitor for suspicious authentication attempts
🧯 If You Can't Patch
- Isolate affected devices from untrusted networks
- Implement strict access controls and monitor for unusual memory access patterns
🔍 How to Verify
Check if Vulnerable:
Check Android security patch level in Settings > About phone > Android version. If before April 2025, device is vulnerable.Check Version:
adb shell getprop ro.build.version.security_patchVerify Fix Applied:
Verify Android security patch level shows April 2025 or later in Settings > About phone > Android version📡 Detection & Monitoring
Log Indicators:
- Unusual memory access patterns in system logs
- Multiple authentication attempts followed by SAEMM component access
Network Indicators:
- Network traffic to SAEMM services from unexpected sources
- Repeated connection attempts to radio message services
