**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.

**How could an attacker exploit this vulnerability?** An authenticated attacker could run a specially crafted application on a vulnerable Hyper-V guest to exploit this vulnerability which, if successful, could potentially interact with processes of another Hyper-V guest hosted on the same Hyper-V host.

**According to the CVSS metric, privileges required is low (PR:L). What does that mean for this vulnerability?** Any authenticated attacker could trigger this vulnerability. It does not require admin or other elevated privileges.

**What type of information could be disclosed by this vulnerability?** An attacker who successfully exploited this vulnerability could potentially read small portions of heap memory.

**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.

**According to the CVSS metric, privileges required is high (PR:H). What does that mean for this vulnerability?** Successful exploitation of this vulnerability requires an attacker to compromise admin credentials on the device.

**What type of information could be disclosed by this vulnerability?** An attacker who successfully exploited this vulnerability could potentially read small portions of stack memory.

**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.

**According to the CVSS metric, user interaction is required (UI:R). What interaction would the user have to do?** This vulnerability could be triggered when a malicious actor spoofs a machine with the same name that a user is searching for.

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