Nov 2026: Windows Installer Elevation of Privilege Vulnerability
CVE-2026-105545
7 - High
- November 10, 2026
An elevation of privilege vulnerability exists in the Windows Installer when the Windows Installer fails to properly sanitize input leading to an insecure library loading behavior. A locally authenticated attacker could run arbitrary code with elevated system privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. The security update addresses the vulnerability by correcting the input sanitization error to preclude unintended elevation.

Oct 2026: Windows NDIS Elevation of Privilege Vulnerability
CVE-2026-105007
8.8 - High
- October 13, 2026
An elevation of privilege vulnerability exists in the Network Driver Interface Specification (NDIS) when ndis.sys fails to check the length of a buffer prior to copying memory to it. To exploit the vulnerability, in a local attack scenario, an attacker could run a specially crafted application to elevate the attacker's privilege level. An attacker who successfully exploited this vulnerability could run processes in an elevated context. However, an attacker must first gain access to the local system with the ability to execute a malicious application in order to exploit this vulnerability. The security update addresses the vulnerability by changing how ndis.sys validates buffer length.
