CVE-2025-58409
📋 TL;DR
This GPU driver vulnerability allows non-privileged users to exploit improper GPU system calls, enabling the GPU hardware to write to arbitrary physical memory pages. This could corrupt kernel and driver memory, potentially altering system behavior. Affected systems include those using vulnerable Imagination Technologies GPU drivers.
💻 Affected Systems
- Imagination Technologies GPU drivers

Ddk by Imaginationtech
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise through kernel memory corruption leading to arbitrary code execution, privilege escalation, or system crash.
Likely Case
System instability, data corruption, or denial of service through memory corruption affecting kernel or driver operations.
If Mitigated
Limited impact if proper access controls restrict GPU access to trusted users only.
🎯 Exploit Status
Exploitation requires understanding of GPU memory management and physical memory addressing.
🛠️ 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 versions. 3. Download and apply the latest patched driver from vendor. 4. Reboot system to load new driver.
🔧 Temporary Workarounds
Restrict GPU Access
linuxLimit GPU device access to trusted users only using permissions.
chmod 600 /dev/gpu_device
setfacl -m u:trusteduser:rw /dev/gpu_device
Disable GPU for Non-Privileged Users
linuxRemove GPU device permissions from non-privileged users.
chmod 660 /dev/gpu_device
chown root:video /dev/gpu_device
🧯 If You Can't Patch
- Implement strict access controls to restrict GPU device usage to essential trusted users only.
- Monitor system logs for unusual GPU access patterns or memory corruption events.
🔍 How to Verify
Check if Vulnerable:
Check GPU driver version against Imagination Technologies advisory list of vulnerable versions.Check Version:
