CVE-2025-0835
📋 TL;DR
This vulnerability allows non-privileged software to make improper GPU system calls that corrupt kernel heap memory. It affects systems using Imagination Technologies GPU drivers. Attackers could potentially escalate privileges or cause system instability.
💻 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).

- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Local privilege escalation to kernel-level access, allowing complete system compromise and potential data exfiltration.
Likely Case
Local privilege escalation allowing attackers to gain elevated permissions on affected systems.
If Mitigated
Denial of service or system instability if exploitation attempts are blocked or fail.
🎯 Exploit Status
Requires local access and ability to execute GPU system calls. Kernel heap corruption exploitation requires specific knowledge of memory layout.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check Imagination Technologies advisory for specific patched driver versions
Vendor Advisory: https://www.imaginationtech.com/gpu-driver-vulnerabilities/
Restart Required: No
Instructions:
1. Visit Imagination Technologies advisory page. 2. Identify affected driver version. 3. Download and install patched GPU driver from vendor. 4. Verify installation and test GPU functionality.
🔧 Temporary Workarounds
Restrict GPU access
LinuxLimit non-privileged user access to GPU system calls through security policies
# Use cgroups or security modules to restrict GPU device access
# Example: chmod 600 /dev/gpu*
# Configure SELinux/AppArmor policies to restrict GPU access
🧯 If You Can't Patch
- Implement strict access controls to prevent non-privileged users from executing GPU-accelerated applications
- Monitor system logs for unusual GPU system call patterns and investigate anomalies
🔍 How to Verify
Check if Vulnerable:
Check GPU driver version against Imagination Technologies advisory. Use 'lspci -k' or 'modinfo' to identify GPU driver versions.Check Version:
modinfo [gpu_driver_module] | grep version # Replace with actual GPU driver module nameVerify Fix Applied:
Verify installed GPU driver version matches patched version from vendor advisory. Test GPU functionality remains operational.📡 Detection & Monitoring
Log Indicators:
- Unusual GPU system call patterns from non-privileged users
- Kernel panic or oops messages related to GPU or memory corruption
- Failed privilege escalation attempts
Network Indicators:
- None - this is a local vulnerability
SIEM Query:
