CVE-2016-10412
📋 TL;DR
This CVE describes an integer overflow vulnerability in Qualcomm memory API functions on Android devices with specific Qualcomm chipsets. Successful exploitation could lead to buffer overflow, potentially allowing remote code execution or privilege escalation. Affected devices include Android smartphones and wearables using vulnerable Qualcomm Snapdragon and MDM processors before April 2018 security patches.
💻 Affected Systems
- Android devices with Qualcomm Snapdragon Mobile, Snapdragon Wear, Small Cell SoC, MDM, and SD series processors
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Remote attacker gains full control of device, executes arbitrary code with kernel privileges, and potentially creates persistent backdoor.
Likely Case
Local attacker or malicious app escalates privileges to gain unauthorized access to system resources and sensitive data.
If Mitigated
Attack fails due to ASLR, stack canaries, or other memory protections; device may crash or become unstable.
🎯 Exploit Status
Exploitation requires understanding of Qualcomm memory management and chipset-specific implementation details. No public exploit code available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Android security patch level 2018-04-05 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 via Settings > System > System update. 3. For devices no longer receiving updates, contact manufacturer for firmware updates or consider device replacement.
🔧 Temporary Workarounds
No effective workarounds
allThis is a firmware/driver-level vulnerability requiring vendor patches. No configuration changes or software workarounds can mitigate the core vulnerability.
🧯 If You Can't Patch
- Isolate affected devices from untrusted networks and limit exposure to potential attack vectors
- Implement strict application vetting and only install apps from trusted sources to reduce attack surface
🔍 How to Verify
Check if Vulnerable:
Check Android security patch level: Settings > About phone > Android security patch level. If date is before April 2018, device is vulnerable.Check Version:
adb shell getprop ro.build.version.security_patchVerify Fix Applied:
Verify security patch level shows April 2018 or later. Check Qualcomm chipset firmware version if available through manufacturer tools.📡 Detection & Monitoring
