Out-of-bounds read in Windows NTFS allows an authorized attacker to elevate privileges locally.
AnalysisAI
Privilege escalation via an out-of-bounds read in the Windows NTFS kernel driver (CWE-125) enables a local attacker with standard user-level access to gain SYSTEM-level control of the affected host. The vulnerability spans an exceptionally broad range of Windows versions - from Windows 10 1607 and Windows Server 2012 through Windows 11 26H1 and Windows Server 2025 - making virtually every unpatched Windows environment in the field potentially exposed. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must have local code execution as a standard (low-privileged) user on the target Windows system, corresponding to PR:L and AV:L in the CVSS vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 7.8 score accurately characterizes a local privilege escalation with high impact across all three pillars (C:H/I:H/A:H). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the vendor-released patch via Windows Update or the Microsoft Update Catalog - exact patched build thresholds are confirmed in the EUVD data: Windows 10 22H2 must reach 10.0.19045.7725 or later, Windows 11 24H2/25H2 must reach 10.0.26100.9445, Windows Server 2025 must reach 10.0.26100.33438 or later, with equivalent thresholds for all other listed versions (see affected_products for full list). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, conduct an inventory of all Windows systems in your environment, categorizing by operating system version (Windows 10, Windows 11, Windows Server editions) and user access type, using your asset management and SIEM tools. …
