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

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

**How could an attacker exploit this vulnerability?** An authenticated attacker could create a crafted vhdx file and can call the vhdmp api with vhdx as one of the arguments.

Access of resource using incompatible type ('type confusion') in Windows Push Notifications allows an authorized attacker to elevate privileges locally.

Exposure of sensitive information to an unauthorized actor in Storage Port Driver allows an authorized attacker to disclose information locally.

Exposure of sensitive information to an unauthorized actor in Windows NT OS Kernel allows an authorized attacker to disclose information locally.

**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.

Time-of-check time-of-use (toctou) race condition in Windows Ancillary Function Driver for WinSock allows an authorized attacker to disclose information locally.

**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 the vulnerability?** To exploit this vulnerability, an authenticated attacker would need to send a specially crafted MSMQ packet to a MSMQ server. This could result in remote code execution on the server side.
