CVE-2024-43704
📋 TL;DR
This vulnerability allows non-privileged user processes to make improper GPU system calls to access the graphics buffers of parent processes. This affects systems using Imagination Technologies GPU drivers where unprivileged users can execute GPU-accelerated applications. The issue enables potential data leakage between processes.
💻 Affected Systems
- Imagination Technologies GPU drivers

⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of sensitive graphical data from other processes, potentially including authentication interfaces, confidential documents, or protected content displayed on screen.
Likely Case
Information disclosure of graphical data from other applications, potentially exposing sensitive information displayed in windows or buffers.
If Mitigated
Limited impact with proper process isolation and minimal sensitive graphical data in memory.
🎯 Exploit Status
Requires local user access and ability to execute GPU-accelerated applications. Exploitation involves crafting specific GPU system calls.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified in reference; check Imagination Technologies advisories
Vendor Advisory: https://www.imaginationtech.com/gpu-driver-vulnerabilities/
Restart Required: Yes
Instructions:
1. Check Imagination Technologies security advisory for specific patch versions
2. Update GPU drivers to patched version
3. Reboot system to load updated drivers
4. Verify driver version after update
🔧 Temporary Workarounds
Restrict GPU access
linuxLimit non-privileged user access to GPU acceleration features
# Configure system to restrict GPU device access
# Use group policies or permissions to control /dev/dri/* access
Process isolation hardening
linuxImplement stricter process isolation and sandboxing for GPU applications
# Use containerization or sandboxing for GPU applications
# Implement mandatory access controls (SELinux/AppArmor)
🧯 If You Can't Patch
- Implement strict user privilege separation and limit GPU device access to trusted users only
- Monitor for unusual GPU system call patterns and implement application whitelisting for GPU-accelerated programs
🔍 How to Verify
Check if Vulnerable:
Check GPU driver version against Imagination Technologies advisory and verify if unprivileged users can access GPU devicesCheck Version:
glxinfo | grep 'OpenGL renderer' or check GPU driver package version via package managerVerify Fix Applied:
Verify GPU driver version matches patched version from vendor advisory and test that unprivileged processes cannot access parent process graphics buffers📡 Detection & Monitoring
Log Indicators:
- Unusual GPU system calls from non-privileged processes
- Multiple failed GPU buffer access attempts
- Processes attempting to access GPU devices without proper permissions
Network Indicators:
- Not applicable - local vulnerability only
