#Role: Windows Hyper-V

**What kind of security feature could be bypassed by exploiting this vulnerability?** This Hyper-V vulnerability relates to a Virtual Machine Switch with virtual networking in Hyper-V Network Virtualization (HNV). It might be possible to bypass extended ACLs and other Windows security feature checks. See Create Security Policies with Extended Port Access Control Lists for information about extended ACLs.

**According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to win a race condition.

**Why is Scope marked as Changed for this vulnerability?** Successful exploitation of this vulnerability would allow a Hyper-V guest to affect the functionality of the Hyper-V host.

**What type of information could be disclosed by this vulnerability?** The type of information that could be disclosed if an attacker successfully exploited this vulnerability is the contents of Kernel memory. An attacker could read the contents of Kernel memory from a user mode process.

**What type of information could be disclosed by this vulnerability?** The type of information that could be disclosed if an attacker successfully exploited this vulnerability is the contents of Kernel memory. An attacker could read the contents of Kernel memory from a user mode process.

**According to the CVSS score, the attack vector is Local. Why does the CVE title indicate that this is a Remote Code Execution?** The word **Remote** in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. For example, when the score indicates that the **Attack Vector** is **Local** and **User Interaction** is **Required**, this could describe an exploit in which an attacker, through social engineering, convinces a victim to download and open a specially crafted file from a website which leads to a local attack on their computer.
