DescriptionCVE.org
Out-of-bounds read in Windows NTFS allows an authorized attacker to elevate privileges locally.
Executive ViewAI
CVE-2026-25175 is a high-severity Windows NTFS vulnerability that allows authorized users with local access to escalate their privileges to administrator or system level. This poses a significant risk to organizations where insider threats exist or where shared systems have multiple user accounts, potentially compromising sensitive data and system integrity.
Restrict local user account creation and login privileges; implement application whitelisting to prevent unauthorized privilege escalation tools; enforce strict file system access controls (NTFS permissions); segment networks to limit lateral movement from compromised user accounts; deploy endpoint detection and response (EDR) solutions to monitor for privilege escalation attempts; disable unnecessary local services; require multi-factor authentication for administrative access; monitor and audit local account creation and group membership changes.

SSVC AssessmentENISA
Priority Score
Attack Technique
A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.
Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
