CVE-2025-0478
📋 TL;DR
This vulnerability allows non-privileged software to perform unauthorized GPU system calls that can read and write arbitrary physical memory pages. This could lead to kernel and driver memory corruption, potentially altering system behavior. Affected systems include those using vulnerable Imagination Technologies GPU drivers.
💻 Affected Systems

⚠️ Risk & Real-World Impact
Worst Case
Kernel memory corruption leading to system compromise, privilege escalation, or denial of service through critical system component manipulation.
Likely Case
Data corruption in kernel or driver memory causing system instability, crashes, or unpredictable behavior in affected applications.
If Mitigated
Limited impact with proper memory isolation and GPU driver sandboxing, potentially only affecting GPU-specific operations.
🎯 Exploit Status
Exploitation requires local access and knowledge of GPU system calls; memory manipulation requires precise targeting.
🛠️ 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: No
Instructions:
1. Visit Imagination Technologies advisory. 2. Identify affected driver version. 3. Download and apply the latest patched driver from vendor. 4. Verify installation.
🔧 Temporary Workarounds
Restrict GPU access
allLimit non-privileged user access to GPU functionality through system permissions or sandboxing.
Use OS-specific access control (e.g., SELinux, AppArmor) to restrict GPU device access
🧯 If You Can't Patch
- Implement strict least-privilege access controls for GPU resources
- Monitor system logs for unusual GPU driver activity or memory access patterns
🔍 How to Verify
Check if Vulnerable:
Check GPU driver version against Imagination Technologies advisory; use 'lspci -k' or similar to identify GPU and driver.
Check Version:
Use OS-specific commands like 'modinfo' for driver modules or check system information tools.
Verify Fix Applied:
Confirm GPU driver version matches patched version from vendor advisory; test GPU functionality remains stable.
