CVE-2025-25180
📋 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 potentially corrupt kernel or driver memory, 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).

⚠️ Risk & Real-World Impact
Worst Case
Kernel memory corruption leading to system compromise, privilege escalation, or complete system instability/crash.
Likely Case
Application crashes, data corruption in GPU-accelerated applications, or limited privilege escalation within GPU context.
If Mitigated
Contained to GPU sandbox with no kernel impact if proper GPU memory isolation is enforced.
🎯 Exploit Status
Exploitation requires understanding of GPU memory management and physical memory addressing. Local access needed.
🛠️ 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 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
chmod 600 /dev/dri/renderD*
chown root:video /dev/dri/renderD*
Disable GPU acceleration
allDisable GPU features for untrusted applications
🧯 If You Can't Patch
- Implement strict user privilege separation to limit GPU device access
- Monitor for unusual GPU memory access patterns or system instability
