CVE-2020-0504
📋 TL;DR
A buffer overflow vulnerability in Intel Graphics Drivers allows authenticated local users to potentially escalate privileges or cause denial of service. This affects systems with vulnerable Intel graphics drivers installed. Attackers need local access to exploit this vulnerability.
💻 Affected Systems
- Intel Graphics Drivers
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An authenticated attacker gains SYSTEM/root privileges, enabling complete system compromise, data theft, or persistent backdoor installation.
Likely Case
Local privilege escalation allowing attackers to bypass security controls, install malware, or access restricted resources.
If Mitigated
Limited impact with proper privilege separation and minimal user access rights, though DoS remains possible.
🎯 Exploit Status
Requires local authenticated access and knowledge of buffer overflow exploitation techniques.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 15.40.44.5107, 15.45.30.5103, or 26.20.100.7158 and later

Restart Required: Yes
Instructions:
1. Visit Intel Driver & Support Assistant or download center. 2. Check current graphics driver version. 3. Download and install updated driver version 15.40.44.5107, 15.45.30.5103, or 26.20.100.7158 or later. 4. Restart system.
🔧 Temporary Workarounds
Restrict Local User Access
allLimit local user accounts and implement least privilege to reduce attack surface
🧯 If You Can't Patch
- Implement strict access controls and limit local user privileges
- Monitor for suspicious local privilege escalation attempts and driver-related crashes
🔍 How to Verify
Check if Vulnerable:
Check Intel graphics driver version in Device Manager (Windows) or via 'lspci -v' and driver info (Linux). Compare against vulnerable versions.Check Version:
Windows: Device Manager > Display adapters > Properties > Driver tab. Linux: Check driver version via system logs or package manager.Verify Fix Applied:
Confirm driver version is 15.40.44.5107, 15.45.30.5103, 26.20.100.7158 or later after update.📡 Detection & Monitoring
Log Indicators:
- Unexpected driver crashes (Event ID 1001 on Windows)
- Failed privilege escalation attempts
- Suspicious process creation from graphics-related executables
Network Indicators:
- Not network exploitable - focus on host-based detection
SIEM Query:
EventID=1001 AND Source="Display" OR ProcessName="igfx*" AND ParentProcess!="explorer.exe"
