CVE-2025-0468
📋 TL;DR
This GPU driver vulnerability allows non-privileged users to make improper GPU system calls that can write to arbitrary physical memory pages. This could enable attackers to corrupt kernel or driver memory, potentially altering system behavior. Affects systems using Imagination Technologies GPU drivers.
💻 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
Kernel memory corruption leading to system compromise, privilege escalation, or denial of service through system instability.
Likely Case
Local privilege escalation allowing attackers to gain elevated privileges on affected systems.
If Mitigated
Limited impact if proper access controls restrict GPU access to trusted users only.
🎯 Exploit Status
Requires local access and GPU system call knowledge; not trivial but feasible for skilled attackers
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific patched driver versions
Vendor Advisory: https://www.imaginationtech.com/gpu-driver-vulnerabilities/
Restart Required: Yes
Instructions:
1. Check Imagination Technologies advisory for affected driver versions. 2. Update GPU drivers to patched version from vendor. 3. Reboot system to load new driver.
🔧 Temporary Workarounds
Restrict GPU access
linuxLimit GPU device access to trusted users only using filesystem permissions
chmod 600 /dev/dri/renderD128
chown root:root /dev/dri/renderD128
Disable GPU acceleration
allDisable GPU acceleration features if not required for system operation
🧯 If You Can't Patch
- Implement strict access controls to limit GPU device access to essential users only
- Monitor system logs for unusual GPU-related activity or privilege escalation attempts
🔍 How to Verify
Check if Vulnerable:
Check GPU driver version against vendor advisory; systems with vulnerable Imagination GPU drivers are affectedCheck Version:
lspci -v | grep -i imagination (Linux) or check GPU driver version in system settingsVerify Fix Applied:
Verify GPU driver version matches patched version from vendor advisory📡 Detection & Monitoring
Log Indicators:
- Unusual GPU system calls from non-privileged users
- Failed privilege escalation attempts
- Kernel panic or instability
Network Indicators:
- None - local exploit only
