Summary
Clevo’s UEFI firmware update packages, including B10717.exe, inadvertently contained private signing keys used for Boot Guard and Boot Policy Manifest verification. The exposure of these keys could allow attackers to sign malicious firmware that appears trusted by affected systems, undermining the integrity of the early boot process.
