Summary
A security feature bypass vulnerability exists when Windows fails to properly handle token relationships.An attacker who successfully exploited the vulnerability could allow an application with a certain integrity level to execute code at a different integrity level, leading to a sandbox escape.The update addresses the vulnerability by correcting how Windows handles token relationships, aka 'Windows Token Security Feature Bypass Vulnerability'.
