CVE-2016-10484
📋 TL;DR
This vulnerability allows buffer overflow attacks in Qualcomm Snapdragon chipsets used in Android devices. An attacker can exploit improper buffer size calculations in RPMB listener registration to execute arbitrary code or cause denial of service. Affected devices include Android smartphones, wearables, and automotive systems with specific Qualcomm chipsets.
💻 Affected Systems
- Android devices with Qualcomm Snapdragon chipsets: Automobile, Mobile, Wear platforms
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution with kernel privileges leading to complete device compromise, data theft, or persistent backdoor installation.
Likely Case
Device crash/reboot (denial of service) or limited code execution in kernel context.
If Mitigated
No impact if patched; limited impact if device has exploit mitigations like ASLR and NX.
🎯 Exploit Status
Requires local access or malicious app installation. No public exploit code available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Android security patch level April 5, 2018 or later
Vendor Advisory: https://source.android.com/security/bulletin/2018-04-01
Restart Required: Yes
Instructions:
1. Check device security patch level in Settings > About phone > Android security patch level. 2. If before April 2018, update to latest Android version via Settings > System > System update. 3. For enterprise devices, push updates via MDM. 4. For embedded/IoT devices, contact manufacturer for firmware updates.
🔧 Temporary Workarounds
Disable unnecessary RPMB listeners
androidReduce attack surface by disabling unused RPMB functionality if possible
🧯 If You Can't Patch
- Isolate affected devices on network segments with strict access controls
- Implement application allowlisting to prevent malicious app installation
🔍 How to Verify
Check if Vulnerable:
Check Android security patch level: Settings > About phone > Android security patch level. If date is before April 5, 2018, device is vulnerable.Check Version:
adb shell getprop ro.build.version.security_patchVerify Fix Applied:
Confirm security patch level shows April 2018 or later. Check Qualcomm chipset version matches affected list.📡 Detection & Monitoring
