## How to fix

- Fixed in 1.0.64.12 (build from 09-07-2026)

## Technical details

The MEARWService driver component relies solely on the operating system's built-in signature checks rather than performing its own validation of loaded components, creating a validation gap. A privileged local attacker can exploit this to load unsigned or malicious drivers, resulting in persistent denial of service and leaving the system unprotected from malware. The vulnerability requires local access and elevated privileges.
