Heap-based buffer overflow in Microsoft Office allows an unauthorized attacker to execute code locally.

**According to the CVSS metric, the attack vector is network (AV:N), user interaction is required (UI:R), and privileges required are none (PR:N). What does that mean for this vulnerability?** Exploitation of this vulnerability requires an unauthorized attacker to wait for a user to initiate a connection to a malicious server that the attacker has set up prior to the user connecting.

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

Buffer over-read in Windows TDX.sys allows an authorized attacker to elevate privileges locally.

**According to the CVSS metric, the attack vector is network (AV:N) and the user interaction is required (UI:R). What is the target context of the remote code execution?** This attack requires an admin user on the client to connect to a malicious server, and that could allow the attacker to gain code execution on the client.

Integer overflow or wraparound in HID class driver allows an authorized attacker to elevate privileges locally.

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

Out-of-bounds read in Windows Hyper-V allows an authorized attacker to execute code over an adjacent network.

Use after free in Windows Universal Plug and Play (UPnP) Device Host allows an authorized attacker to elevate privileges over an adjacent network.

Improper link resolution before file access ('link following') in Windows AppX Deployment Service allows an authorized attacker to elevate privileges locally.
