CVE-2025-58411
📋 TL;DR
This vulnerability allows non-privileged users to exploit improper GPU resource management through system calls, potentially leading to use-after-free conditions. It affects systems running Imagination Technologies GPU drivers where users can execute GPU operations. The vulnerability could enable local privilege escalation or system compromise.
💻 Affected Systems
- Imagination Technologies GPU drivers
📦 What is this software?
Ddk by Imaginationtech
⚠️ Risk & Real-World Impact
Worst Case
Local privilege escalation to kernel-level access, enabling full system compromise, data theft, or persistent backdoor installation.
Likely Case
Local privilege escalation allowing attackers to gain elevated privileges on the affected system.
If Mitigated
Limited impact if proper access controls restrict GPU access to trusted users only.
🎯 Exploit Status
Exploitation requires local access and ability to make GPU system calls; no public exploit code is mentioned.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific patched versions
Vendor Advisory: https://www.imaginationtech.com/gpu-driver-vulnerabilities/
Restart Required: Yes
Instructions:
1. Visit the vendor advisory URL. 2. Identify affected driver versions. 3. Download and install the latest patched GPU driver from Imagination Technologies. 4. Reboot the system to apply changes.
🔧 Temporary Workarounds
Restrict GPU Access
linuxLimit GPU system call access to privileged users only to prevent exploitation.
# Linux: Use cgroups or security modules to restrict GPU device access
# Example: chmod 600 /dev/gpu_device
🧯 If You Can't Patch
- Implement strict access controls to prevent non-privileged users from executing GPU operations.
- Monitor system logs for unusual GPU activity or privilege escalation attempts.
🔍 How to Verify
Check if Vulnerable:
Check GPU driver version against vendor advisory; if using affected Imagination GPU driver versions, system is vulnerable.Check Version:
# Linux: Check GPU driver version via system logs or vendor tools
# Example: dmesg | grep -i gpu
# Or use vendor-specific commands from Imagination TechnologiesVerify Fix Applied:
Verify GPU driver version has been updated to patched version specified in vendor advisory.📡 Detection & Monitoring
Log Indicators:
- Unusual GPU system calls from non-privileged users
- Kernel panic or crash logs related to GPU drivers
- Failed privilege escalation attempts
Network Indicators:
- Not applicable; this is a local vulnerability
