CVE-2025-6573

9.8 CRITICAL

📋 TL;DR

This vulnerability allows kernel software running in an untrusted execution environment to leak sensitive information from the trusted execution environment (TEE). It affects systems using Imagination Technologies GPU drivers with TEE implementations. The high CVSS score indicates critical impact potential.

💻 Affected Systems

Products:
  • Imagination Technologies GPU drivers with TEE implementations
Versions: Specific versions not detailed in reference; likely multiple affected versions
Operating Systems: Android, Linux-based systems using Imagination GPU drivers
Default Config Vulnerable: ⚠️ Yes
Notes: Affects systems with Imagination GPU hardware and TEE implementations; mobile devices and embedded systems are primary targets.

⚠️ 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).

Recommended Actions:
  1. Review the CVE details at NVD
  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete compromise of TEE-protected data including cryptographic keys, biometric data, DRM content, and secure payment information, leading to total system compromise.

🟠

Likely Case

Leakage of sensitive TEE-protected information such as encryption keys or authentication tokens, enabling further system exploitation.

🟢

If Mitigated

Limited information leakage if proper TEE isolation and access controls are implemented, but still potentially exposing some protected data.

🌐 Internet-Facing: MEDIUM
🏢 Internal Only: HIGH

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: MEDIUM

Exploitation requires kernel-level access in REE; no public exploit details available yet.

🛠️ 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. Check Imagination Technologies security advisory for affected versions. 2. Obtain updated GPU drivers from device manufacturer or Imagination. 3. Apply driver updates following vendor instructions. 4. Reboot system to activate new drivers.

🔧 Temporary Workarounds

Disable TEE functionality

linux

Temporarily disable Trusted Execution Environment features if not required

echo 0 > /sys/kernel/tee/enable

Restrict kernel module loading

linux

Prevent unauthorized kernel modules from loading

echo 1 > /proc/sys/kernel/modules_disabled

🧯 If You Can't Patch

  • Isolate affected systems from untrusted networks and limit user access
  • Implement strict monitoring for unusual TEE access patterns and kernel activities

🔍 How to Verify

Check if Vulnerable:

Check GPU driver version and compare against Imagination's advisory; examine dmesg for TEE-related errors

Check Version:

dmesg | grep -i imagination || cat /proc/version

Verify Fix Applied:

Verify updated GPU driver version is installed; test TEE functionality remains operational

📡 Detection & Monitoring

Log Indicators:

  • Unusual TEE access patterns in kernel logs
  • GPU driver crash or abnormal behavior logs
  • Unexpected kernel module loading

Network Indicators:

  • Unusual outbound connections from kernel processes
  • Suspicious inter-process communication patterns

SIEM Query:

source="kernel" AND ("TEE" OR "imagination" OR "GPU") AND (error OR warning OR abnormal)
