Windows Client Server Run-time Subsystem (CSRSS) Elevation of Privilege Vulnerability

According to the CVSS metric, a successful exploitation could lead to a scope change (S:C). What does this mean for this vulnerability?
A locally authenticated attacker could send specially crafted data to the local CSRSS service to elevate their privileges from AppContainer to SYSTEM. Because the AppContainer environment is considered a defensible security boundary, any process that is able to bypass the boundary is considered a change in Scope. The attacker could then execute code or access resources at a higher integrity level than that of the AppContainer execution environment.
