CVE-2024-12837
📋 TL;DR
This vulnerability allows non-privileged software to make improper GPU system calls that corrupt kernel heap memory, potentially leading to system compromise. It affects systems using Imagination Technologies GPU drivers. The impact is limited to local attackers who can run code on the target system.
💻 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).

- Review the CVE details at NVD
- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Local privilege escalation to kernel-level access, allowing full system compromise, data theft, or persistent backdoor installation.
Likely Case
Local denial of service through system crashes or instability, with potential for limited privilege escalation in targeted attacks.
If Mitigated
Minimal impact if proper privilege separation and least privilege principles are followed, with only application-level effects.
🎯 Exploit Status
Exploitation requires understanding of GPU system calls and kernel memory management. Local access and ability to execute code needed.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Imagination Technologies advisory for specific patched driver versions
Vendor Advisory: https://www.imaginationtech.com/gpu-driver-vulnerabilities/
Restart Required: No
Instructions:
1. Visit Imagination Technologies security advisory page. 2. Identify affected driver version for your hardware. 3. Download and install updated GPU driver from vendor. 4. Verify installation and test GPU functionality.
🔧 Temporary Workarounds
Restrict GPU access
LinuxLimit non-privileged user access to GPU system calls through security policies
# Use Linux security modules like SELinux or AppArmor to restrict GPU device access
# Example: chmod 600 /dev/dri/renderD* (adjust for your GPU device)
🧯 If You Can't Patch
- Implement strict least privilege principles - ensure users only have necessary permissions
- Isolate GPU-using applications in containers or VMs with limited host access
🔍 How to Verify
Check if Vulnerable:
Check GPU driver version against Imagination Technologies advisory. Use 'lspci -k' to identify GPU and driver in use.Check Version:
glxinfo | grep 'OpenGL version' OR check /sys/class/drm/*/device/uevent for driver infoVerify Fix Applied:
Verify updated driver version matches patched version in vendor advisory. Test GPU functionality remains operational.📡 Detection & Monitoring
