CVE-2025-25179
📋 TL;DR
This vulnerability allows non-privileged users to exploit GPU driver flaws to write to arbitrary physical memory pages. It affects systems with Imagination Technologies GPU drivers. Attackers could potentially bypass memory protection mechanisms to gain elevated privileges or cause system instability.
💻 Affected Systems
- Imagination Technologies GPU drivers
📦 What is this software?
Ddk by Imaginationtech
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise via privilege escalation to kernel-level access, allowing arbitrary code execution, data theft, or system crash.
Likely Case
Local privilege escalation allowing attackers to gain elevated permissions on affected systems, potentially leading to data access or further system exploitation.
If Mitigated
Limited impact if proper access controls restrict non-privileged user access to affected systems and GPU resources are properly isolated.
🎯 Exploit Status
Requires local access and knowledge of GPU system calls. Exploitation may require specific conditions or driver configurations.
🛠️ 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. Check Imagination Technologies security advisory for affected versions. 2. Update GPU drivers to patched version from official vendor sources. 3. Reboot system to load new driver.
🔧 Temporary Workarounds
Restrict GPU access
linuxLimit non-privileged user access to GPU devices and system calls
chmod 600 /dev/dri/*
setfacl -m u:root:rw- /dev/dri/*
Disable GPU passthrough
allIn virtualization environments, disable GPU passthrough to guest VMs
🧯 If You Can't Patch
- Implement strict access controls to prevent non-privileged users from accessing GPU resources
- Isolate affected systems from critical networks and monitor for suspicious GPU-related activity
🔍 How to Verify
Check if Vulnerable:
Check GPU driver version against Imagination Technologies advisory. Use: lspci -v | grep -i imaginationCheck Version:
modinfo -F version [gpu_driver_module] or check /sys/class/drm/*/device/ueventVerify Fix Applied:
Verify GPU driver version matches patched version from vendor advisory. Check system logs for successful driver load.📡 Detection & Monitoring
