CVE-2025-12050

7.8 HIGH

📋 TL;DR

This vulnerability allows local attackers to trigger a buffer overflow in certain driver components by manipulating registry values. It affects systems running specific versions of software that use vulnerable driver packages, potentially leading to privilege escalation or system compromise.

💻 Affected Systems

Products:
  • Insyde Software products using vulnerable driver packages
Versions: Specific versions not detailed in advisory; check vendor advisory for exact affected versions
Operating Systems: Windows
Default Config Vulnerable: ⚠️ Yes
Notes: Affects systems with the vulnerable driver packages installed. The vulnerability is in how drivers handle registry queries using RTL_QUERY_REGISTRY_DIRECT flag.

⚠️ 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 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/root privileges, enabling further lateral movement within the network.

🟢

If Mitigated

Limited impact with proper access controls and monitoring, potentially causing system instability or crashes without full compromise.

🌐 Internet-Facing: LOW - This requires local access to the system and cannot be directly exploited over the internet.
🏢 Internal Only: HIGH - Malicious insiders or compromised user accounts could exploit this to gain elevated privileges and move laterally within the network.

🎯 Exploit Status

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

Exploitation requires local access and ability to write to specific registry keys. The buffer overflow condition can be triggered by manipulating registry values.

🛠️ 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 vendor advisory URL. 2. Identify affected products and versions. 3. Download and apply the appropriate patch from the vendor. 4. Restart the system to complete the installation.

🔧 Temporary Workarounds

Registry Access Restriction

windows

Restrict write access to the vulnerable registry keys to prevent untrusted applications from modifying them

reg add "HKLM\SYSTEM\CurrentControlSet\Services\[VulnerableService]" /v "RegistryKeyPermissions" /t REG_DWORD /d 4 /f

Driver Removal

windows

Remove or disable the vulnerable driver packages if not essential for system operation

sc stop [VulnerableService]
sc delete [VulnerableService]

🧯 If You Can't Patch

  • Implement strict access controls to limit who can run applications on affected systems
  • Deploy application whitelisting to prevent execution of untrusted applications

🔍 How to Verify

Check if Vulnerable:

Check system for presence of vulnerable driver packages mentioned in vendor advisory. Review installed drivers and compare against affected versions.

Check Version:

driverquery /v | findstr /i "[DriverName]"

Verify Fix Applied:

Verify driver version after patch installation matches patched version from vendor advisory. Check that registry-related buffer overflow protections are in place.

📡 Detection & Monitoring

Log Indicators:

  • Unusual registry modification attempts to driver-related keys
  • Driver crash events in System logs
  • Privilege escalation attempts from standard user accounts

Network Indicators:

  • Lateral movement following local privilege escalation
  • Unusual outbound connections from previously compromised systems

SIEM Query:

EventID=4656 OR EventID=4663 AND ObjectName="*\Services\*" AND AccessMask="0x2"
