Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly mitigates the CVE by requiring timely remediation of the specific out-of-bounds read flaw in Windows NTFS through vendor patches.
Implements memory safeguards such as ASLR and DEP to protect against exploitation of out-of-bounds reads leading to privilege escalation.
Enforces least privilege for local accounts, limiting the privileges exploitable by low-privileged attackers targeting this NTFS vulnerability.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Out-of-bounds read in Windows NTFS driver directly enables local privilege escalation from low-privileged context with no user interaction, matching T1068 Exploitation for Privilege Escalation.
NVD Description
Out-of-bounds read in Windows NTFS allows an authorized attacker to elevate privileges locally.
Deeper analysisAI
CVE-2026-25175 is an out-of-bounds read vulnerability, classified under CWE-125, affecting the Windows NTFS file system component. Published on 2026-03-10T18:18:32.520, it carries a CVSS v3.1 base score of 7.8 (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential for significant impacts on confidentiality, integrity, and availability.
A local attacker with low privileges (PR:L) can exploit this vulnerability with low attack complexity and no user interaction required. Successful exploitation enables local privilege escalation, allowing the attacker to gain higher-level access on the affected Windows system.
