CVE-2025-12052
📋 TL;DR
This vulnerability allows local attackers to cause a buffer overflow by manipulating registry values that drivers read using the RTL_QUERY_REGISTRY_DIRECT flag. It affects systems running vulnerable versions of Insyde Software's tool packages. Successful exploitation could lead to privilege escalation or system compromise.
💻 Affected Systems
- Insyde Software tool packages with vulnerable 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).

- 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
Complete system compromise with kernel-level code execution, allowing attackers to install persistent malware, steal sensitive data, or disable security controls.
Likely Case
Local privilege escalation from a standard user account to SYSTEM/administrator privileges, enabling further lateral movement within the network.
If Mitigated
Limited impact if proper access controls restrict local user privileges and registry modification permissions.
🎯 Exploit Status
Requires local access and ability to modify registry values; buffer overflow exploitation requires specific knowledge of memory layout.
