CVE-2020-0510
📋 TL;DR
This vulnerability is an out-of-bounds read in certain Intel Graphics Drivers that could allow an authenticated local user to potentially escalate privileges. It affects systems with vulnerable Intel graphics drivers installed. The attacker needs 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 on the affected system, enabling complete system compromise.
Likely Case
Local privilege escalation allowing an authenticated user to gain higher privileges than intended.
If Mitigated
Limited impact if proper access controls and least privilege principles are enforced.
🎯 Exploit Status
Requires local authenticated access and knowledge of driver internals.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 15.45.31.5127 or 15.40.45.5126 and later
Vendor Advisory: https://www.intel.com/content/www/us/en/security-center/advisory/intel-sa-00369.html
Restart Required: Yes
Instructions:
1. Visit Intel's driver download page. 2. Download the latest graphics driver for your Intel GPU. 3. Install the driver following on-screen instructions. 4. Restart the system.
🔧 Temporary Workarounds
Restrict local user access
allLimit local user accounts and enforce least privilege to reduce attack surface.
🧯 If You Can't Patch
- Implement strict access controls and limit local user privileges
- Monitor for unusual 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 -k' and driver info (Linux).Check Version:
Windows: dxdiag or Device Manager; Linux: 'modinfo i915' or check driver version in system logsVerify Fix Applied:
Verify driver version is 15.45.31.5127 or 15.40.45.5126 or later after update.📡 Detection & Monitoring
