**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 gather information specific to the environment of the targeted component.

**According to the CVSS metric, a successful exploitation could lead to a scope change (S:C). What does this mean for this vulnerability?** Successful exploitation of this vulnerability could allow a Hyper-V guest to affect the functionality of the Hyper-V host.

**Upon successful exploitation, what privileges could an attacker gain?** An attacker who successfully exploited this vulnerability could gain administrator privileges.

**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 sensitive information.

**Upon successful exploitation, what privileges could an attacker gain?** An attacker who successfully exploited this vulnerability could gain administrator privileges.

**What privileges could an attacker gain?** An attacker who successfully exploited this vulnerability could gain SYSTEM privileges.

**What is RTOS?** Azure RTOS is an embedded development suite including a small but powerful operating system that provides reliable, ultra-fast performance for resource-constrained devices. See Azure RTOS Overview for more information. **What is Azure RTOS GUIX Studio?** Azure GUIX embedded GUI is Microsoft’s advanced, industrial grade GUI solution designed specifically for deeply embedded, real-time, and IoT applications. Microsoft also provides a full-featured WYSIWYG desktop design tool named Azure RTOS GUIX Studio, which allows developers to design their GUI on the desktop and generate Azure RTOS GUIX embedded GUI code that can then be exported to the target. See Azure RTOS GUIX and Azure RTOS GUIX Studio for more information.

**What type of privileges could an attacker gain through this vulnerability?** A domain user could use this vulnerability to elevate privileges to SYSTEM assigned integrity level.

**What privileges could an attacker gain?** An attacker who successfully exploited this vulnerability could gain SYSTEM privileges.

**According to the CVSS metric, the attack vector is local (AV:L). 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.
