Windows Kernel Security Feature Bypass Vulnerability

What kind of security feature could be bypassed by successfully exploiting this vulnerability?
An attacker who successfully exploited this vulnerability could bypass the Windows Arbitrary Code Guard exploit protection feature.

According to the CVSS metric, successful exploitation of this vulnerability could lead to some loss of integrity (I:L) and some loss of availability (A:L). What does that mean for this vulnerability?
An attacker can craft a malicious file that would bypass the Arbitrary Code Guard (ACG) exploit protection feature. However, after ACG is bypassed, while the data processed or protected can't be fully trusted, the attacker does not have full control over an exploited component with only this bypass. As a result, confidentiality of information resources managed by Windows is not in itself compromised (C:N), but both system integrity (I:L) and system availability (A:L) might experience limited compromises by this bypass.
