**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 prepare the target environment to improve exploit reliability.

**What type of information could be disclosed by this vulnerability?** Exploiting this vulnerability could allow the disclosure of certain memory address within kernel space. Knowing the exact location of kernel memory could be potentially leveraged by an attacker for other malicious activities.

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

Use of uninitialized resource in Windows Routing and Remote Access Service (RRAS) allows an unauthorized attacker to disclose information over a network.

Use of uninitialized resource in Windows Trusted Runtime Interface Driver allows an authorized attacker to disclose information locally.

Uncontrolled resource consumption in Remote Desktop Gateway Service allows an unauthorized attacker to deny service over a network.

Use after free in Windows Ancillary Function Driver for WinSock allows an authorized attacker to elevate privileges locally.

**According to the CVSS metrics, successful exploitation of this vulnerability could lead to a high loss of confidentiality (C:H), and some loss of integrity (I:L) and no loss of availability (A:N). What does that mean for this vulnerability?** An attacker who successfully exploited this vulnerability could view sensitive information, a token in this scenario (Confidentiality), and make some changes to disclosed information (Integrity), but they would not be able to affect Availability.

Heap-based buffer overflow in Windows Common Log File System Driver allows an authorized attacker to elevate privileges locally.

Use of hard-coded credentials in Windows Hardware Lab Kit allows an authorized attacker to elevate privileges locally.
