CVE-2024-43705
📋 TL;DR
This vulnerability allows non-privileged software to exploit GPU kernel driver flaws to write to read-only system files mapped into application memory. This affects systems using Imagination Technologies GPU drivers. Attackers could potentially modify critical system files.
💻 Affected Systems
- Imagination Technologies GPU drivers
⚠️ Manual Verification Required
This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.
Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise through modification of critical system files, leading to privilege escalation, persistence, or system instability.
Likely Case
Privilege escalation allowing attackers to gain elevated permissions or modify system configurations.
If Mitigated
Limited impact if proper access controls and driver sandboxing are implemented.
🎯 Exploit Status
Requires local access and ability to execute code as non-privileged user. Exploitation involves manipulating GPU driver memory mappings.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Imagination Technologies advisory for specific patched versions.
Vendor Advisory: https://www.imaginationtech.com/gpu-driver-vulnerabilities/
Restart Required: Yes
Instructions:
1. Visit Imagination Technologies advisory. 2. Identify affected driver version. 3. Download and install patched driver from vendor. 4. Reboot system to apply changes.
🔧 Temporary Workarounds
Restrict GPU driver access
linuxLimit non-privileged user access to GPU driver interfaces through system permissions.
chmod 600 /dev/gpu_device
setfacl -m u:root:rw- /dev/gpu_device
Disable unnecessary GPU features
linuxDisable GPU memory mapping features if not required for system functionality.

🧯 If You Can't Patch
- Implement strict access controls to limit which users can run GPU-accelerated applications.
- Monitor system for unusual file modification attempts and GPU driver activity.
🔍 How to Verify
Check if Vulnerable:
Check GPU driver version against Imagination Technologies advisory. Use: lspci -v | grep -i imaginationCheck Version:
modinfo gpu_driver_module | grep versionVerify Fix Applied:
Verify installed driver version matches patched version from vendor advisory.📡 Detection & Monitoring
