⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with kernel-level access, enabling persistent backdoors, data theft, and disabling of security controls.
Likely Case
Local privilege escalation allowing attackers to gain SYSTEM/root privileges on compromised machines.
If Mitigated
Limited impact if systems are patched and have proper endpoint protection with driver signature enforcement.
🎯 Exploit Status
Requires local access and ability to load/execute code; kernel driver vulnerabilities typically require some technical sophistication
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Latest security update from Paragon
Restart Required: Yes
Instructions:
1. Visit Paragon support page. 2. Download latest security patch. 3. Install patch. 4. Restart system. 5. Verify biontdrv.sys driver version is updated.
🔧 Temporary Workarounds
Disable or remove vulnerable driver
windowsRemove or disable the biontdrv.sys driver to prevent exploitation
sc stop biontdrv
sc delete biontdrv
Remove biontdrv.sys from System32\drivers
Enable driver signature enforcement
windowsEnforce driver signature requirements to prevent loading of unauthorized drivers
bcdedit /set testsigning off
bcdedit /set nointegritychecks off
🧯 If You Can't Patch
- Restrict local access to vulnerable systems and implement strict privilege separation
- Deploy endpoint detection that monitors for suspicious driver loading and kernel memory writes
