CVE-2025-10865
📋 TL;DR
This CVE describes a use-after-free vulnerability in Imagination Technologies GPU drivers where improper reference counting allows non-privileged users to potentially exploit GPU system calls. This could lead to memory corruption and system instability. Affected systems include those using Imagination GPU drivers with vulnerable versions.
💻 Affected Systems
- Imagination Technologies GPU drivers
📦 What is this software?
Ddk by Imaginationtech
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise leading to arbitrary code execution with kernel privileges, potentially allowing attackers to install persistent malware or exfiltrate sensitive data.
Likely Case
System crashes, denial of service, or limited privilege escalation within the GPU context, potentially allowing escape from containerized environments.
If Mitigated
Application crashes or instability without privilege escalation if proper sandboxing and privilege separation are implemented.
🎯 Exploit Status
Exploitation requires understanding of GPU memory management and driver internals. The vulnerability requires local access or ability to execute code on the target system.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Imagination Technologies security advisory for specific patched versions
Vendor Advisory: https://www.imaginationtech.com/gpu-driver-vulnerabilities/
Restart Required: Yes
Instructions:
1. Visit Imagination Technologies security advisory page. 2. Identify affected driver versions. 3. Download and install the latest patched driver version. 4. Reboot the system to ensure driver changes take effect.
🔧 Temporary Workarounds
Disable GPU acceleration for untrusted users
linuxRestrict GPU access to trusted users only to prevent exploitation
# Linux: Restrict GPU device access
chmod 660 /dev/dri/renderD*
# Linux: Use cgroups to restrict GPU access
cgcreate -g devices:gpu -t user:username
# Add appropriate device restrictions to cgroup
Implement strict privilege separation
linuxEnsure applications run with minimal privileges and proper sandboxing
# Use namespaces and capabilities to restrict access
podman run --security-opt=no-new-privileges --cap-drop=ALL --cap-add=CAP_SYS_ADMIN image
# Or use Docker with similar restrictions
🧯 If You Can't Patch
- Implement strict access controls to limit which users can run GPU-accelerated applications
- Monitor system logs for unusual GPU-related activity and implement application allowlisting
🔍 How to Verify
Check if Vulnerable:
Check GPU driver version and compare against Imagination Technologies security advisory. Use 'lspci -k' to identify GPU and driver information on Linux systems.Check Version:
# Linux: Check GPU driver version
modinfo -F version [driver_module_name]
# Or check package manager for driver version
dpkg -l | grep imagination
rpm -qa | grep imaginationVerify Fix Applied:
Verify driver version has been updated to patched version. Test GPU functionality to ensure patch doesn't break required functionality.📡 Detection & Monitoring
Log Indicators:
- Unusual GPU system calls from non-privileged users
- GPU driver crash logs or kernel oops messages
- Multiple failed GPU memory allocation attempts
Network Indicators:
- Not applicable - local vulnerability
