Oct 13, 2026An elevation of privilege vulnerability exists in the Network Driver Interface Specification (NDIS) when ndis.sys fails to check the length of a buffer prior toCVE-2026-105007 · Computers, phones & browsers · Microsoft · reported by secure@microsoft.comHigh 8.8
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.

Gotify server is a simple server for sending and receiving messages in real-time per WebSocket. Prior to 3.0.0, the password change endpoint (POST /current/user/password) accepts a valid client token without requiring the account's current password or another elevated authentication step. An attacker who obtains a client token can set a new password for the associated user, taking control of password authentication and forcing account recovery through an administrator or direct database access. This issue is fixed in version 3.0.0.

Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories.
