CVE-2025-12051
📋 TL;DR
This vulnerability allows local attackers to cause a buffer overflow in certain drivers by manipulating registry values. It affects systems using Insyde Software drivers that improperly handle registry queries with the RTL_QUERY_REGISTRY_DIRECT flag. Attackers could potentially execute arbitrary code with kernel privileges.
💻 Affected Systems
- Insyde Software drivers in tool packages
⚠️ 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).

- Review the CVE details at 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 SYSTEM/kernel level, allowing complete system compromise and persistence.
Likely Case
Local privilege escalation from standard user to administrator/system privileges.
If Mitigated
Limited impact if proper access controls restrict registry modifications and driver loading.
🎯 Exploit Status
Requires local access and ability to write to specific registry keys. Buffer overflow exploitation requires knowledge of memory layout.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Check vendor advisory for specific patched versions
Vendor Advisory: https://www.insyde.com/security-pledge/sa-2025010/
Restart Required: Yes
Instructions:
1. Visit the Insyde security advisory page
2. Identify affected driver versions
3. Download and install updated drivers from vendor
4. Restart system to load patched drivers
🔧 Temporary Workarounds
Restrict registry permissions
windowsLimit write access to registry keys used by vulnerable drivers
reg add "HKLM\SYSTEM\CurrentControlSet\Services\[DriverName]" /v Start /t REG_DWORD /d 4 /f
icacls "HKLM\SYSTEM\CurrentControlSet\Services\[DriverName]" /inheritance:r /grant:r "SYSTEM:(F)" "Administrators:(F)"
Disable vulnerable drivers
windowsPrevent loading of affected drivers if not required
sc config [DriverServiceName] start= disabled
sc stop [DriverServiceName]
🧯 If You Can't Patch
- Implement strict access controls on registry keys to prevent unauthorized modifications
- Use application whitelisting to prevent execution of untrusted applications
🔍 How to Verify
Check if Vulnerable:
Check driver versions against vendor advisory and verify if RTL_QUERY_REGISTRY_DIRECT flag is used in registry operationsCheck Version:
driverquery /v | findstr /i "insyde"Verify Fix Applied:
Verify driver version is updated to patched version and test registry access controls📡 Detection & Monitoring
