CVE-2024-43703
📋 TL;DR
This vulnerability allows non-privileged users to make improper GPU system calls, enabling unauthorized reads and writes of physical memory from GPU hardware. It affects systems with Imagination Technologies GPU drivers where software runs with non-privileged user access. The exploit leverages GPU hardware access to bypass memory protection mechanisms.
💻 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).

- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise including kernel memory corruption, privilege escalation to root/admin, data exfiltration, and persistent backdoor installation.
Likely Case
Privilege escalation allowing attackers to gain elevated system privileges and access sensitive data in memory.
If Mitigated
Limited impact if proper access controls restrict GPU access to trusted applications only.
🎯 Exploit Status
Requires local access and ability to execute code as non-privileged user. GPU-specific knowledge needed for exploitation.
🛠️ 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 page. 2. Identify affected driver versions. 3. Download and apply latest patched GPU drivers. 4. Reboot system to load new drivers.
🔧 Temporary Workarounds
Restrict GPU Access
linuxLimit GPU device access to trusted users only using Linux permissions
chmod 600 /dev/dri/renderD*
chown root:video /dev/dri/renderD*
Disable GPU Acceleration
allDisable GPU acceleration for untrusted applications
🧯 If You Can't Patch
- Implement strict access controls to limit which users can run GPU-accelerated applications
- Isolate GPU-accessible systems in separate network segments with limited trust
🔍 How to Verify
Check if Vulnerable:
Check GPU driver version against Imagination Technologies advisory. Run: lspci -v | grep -i imaginationCheck Version:
modinfo -F version [gpu_driver_module] or check /sys/class/drm/card*/device/ueventVerify Fix Applied:
Verify GPU driver version matches patched version from vendor advisory. Check system logs for successful driver updates.📡 Detection & Monitoring
Log Indicators:
- Unusual GPU system call patterns
- Failed GPU permission attempts from non-privileged users
- Kernel memory access violations
Network Indicators:
- Not applicable - local exploitation only
