CVE-2026-105007
HighCVSS 8.8Exploitation Probability (EPSS)
Elevated risk55th percentile - higher than 55% of all known CVEs
Summary
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.
Risk Assessment
A local attacker could gain elevated privileges and run processes in an elevated context, potentially leading to full system compromise.
Recommendation
Install the latest Windows security updates that include the fix for ndis.sys.
Other vulnerabilities in Windows NDIS
See all- CVE-2026-69396High
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.
- CVE-2026-69357High
Use after free in Windows NDIS allows an authorized attacker to elevate privileges over a network.
- CVE-2026-20936Medium
Out-of-bounds read in Windows NDIS allows an authorized attacker to disclose information via a physical attack.
