CVE-2020-0376
📋 TL;DR
CVE-2020-0376 is an out-of-bounds read vulnerability in Android System-on-Chip (SoC) components that could allow attackers to read sensitive memory contents. This affects Android devices with vulnerable SoC firmware. Attackers could potentially gain unauthorized access to device memory.
💻 Affected Systems
- Android devices with vulnerable SoC components
📦 What is this software?
Android by Google
⚠️ Risk & Real-World Impact
Worst Case
Full device compromise including privilege escalation, data exfiltration, and remote code execution through memory corruption chaining.
Likely Case
Information disclosure of sensitive memory contents, potential denial of service through system crashes.
If Mitigated
Limited impact with proper memory isolation and exploit mitigations like ASLR and stack canaries.
🎯 Exploit Status
Requires local access or malicious app installation. Exploitation depends on specific memory layout and SoC implementation.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Android Security Bulletin October 2020 patches
Vendor Advisory: https://source.android.com/security/bulletin/2020-10-01
Restart Required: Yes
Instructions:
1. Check for Android security updates in device settings. 2. Apply October 2020 or later security patches. 3. Contact device manufacturer for SoC firmware updates if available. 4. Reboot device after update installation.
🔧 Temporary Workarounds
Restrict app installations
androidOnly install apps from trusted sources like Google Play Store to reduce attack surface.
Enable Google Play Protect
androidEnsure Google Play Protect is enabled to detect potentially harmful apps.
🧯 If You Can't Patch
- Isolate vulnerable devices from critical networks and sensitive data
- Implement application allowlisting to prevent unauthorized app execution
🔍 How to Verify
Check if Vulnerable:
Check Android security patch level in Settings > About phone > Android version. If patch level is before October 2020, device is vulnerable.Check Version:
