CVE-2026-69396
HighCVSS 7.1Exploitation Probability (EPSS)
Low risk45th percentile - higher than 45% of all known CVEs
Summary
A use-after-free vulnerability in Windows NDIS allows an authorized attacker to elevate privileges over a network. The issue stems from using memory after it has been freed.
Risk Assessment
An attacker could gain elevated privileges in a network context, potentially leading to network traffic interception or privilege escalation within the system.
Recommendation
Install Windows security updates and monitor network traffic for unusual activities.

See all- CVE-2026-105007High
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.
