Windows Secure Boot Security Feature Bypass Vulnerability
A security feature bypass exists when Windows Secure Boot improperly restricts access to debugging functionality. An attacker who successfully exploited this vulnerability could disclose protected kernel memory.
To exploit the vulnerability, an attacker must gain physical access to the target system prior to the next system reboot.
The security update addresses the vulnerability by preventing access to certain debugging options when Windows Secure Boot is enabled.
