Use after free in Windows NTFS allows an authorized attacker to elevate privileges locally.
AnalysisAI
Local privilege escalation in Windows NTFS exposes a use-after-free condition in the kernel-mode filesystem driver, allowing an authenticated local attacker with low privileges to achieve full SYSTEM-level control. The vulnerability spans virtually the entire supported Windows ecosystem - from Server 2012 through Windows 11 26H1 and Windows Server 2025 - making it broadly applicable in enterprise environments. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an attacker to already have low-privileged, authenticated local code execution on the target Windows system (CVSS PR:L, AV:L). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 7.0 score (AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H) accurately characterizes this as a meaningful but non-trivial local privilege escalation. … 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 Microsoft security update corresponding to the installed Windows version via Windows Update or WSUS. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all Windows systems in your infrastructure (Windows Server 2012 through 2025 and Windows 11 versions through 26H1) and assess exposure scope; prioritize domain controllers, servers hosting critical applications, and systems accessible to contractors or less-trusted user accounts. …
