Protection mechanism failure in Windows Secure Boot allows an authorized attacker to bypass a security feature locally.
According to the CVSS metric, a successful exploitation could lead to a scope change (S:C). What does this mean for this vulnerability? A scope change means that successfully exploiting this vulnerability could allow an attacker to affect security protections beyond the original vulnerable component. In this case, the issue could enable a bypass of Secure Boot and exposure of Virtual Secure Mode (VSM) secrets, impacting a more highly protected security boundary rather than being limited to the initially affected boot component. What kind of security feature could be bypassed by successfully exploiting this vulnerability? An attacker who successfully exploited this vulnerability could bypass Secure Boot.
