Use after free in Virtual Hard Disk (VHD) Miniport Driver allows an authorized attacker to elevate privileges locally.
AnalysisAI
Privilege escalation in the Windows Virtual Hard Disk (VHD) Miniport Driver affects Windows 10, 11, and Server 2016 through 2025, enabling a low-privileged local attacker to achieve full kernel-level control via a use-after-free memory corruption in a kernel-mode driver. The CVSS AC:H rating indicates the exploit path likely requires precise timing - consistent with a race condition in driver memory management - which reduces but does not eliminate real-world risk. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an existing local authenticated session with at minimum standard user (low-privilege) rights, as confirmed by the CVSS PR:L metric - unauthenticated or remote exploitation is not possible per the AV:L vector. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 7.0 score with vector AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H accurately encodes a meaningful local privilege escalation: network-remote exploitation is not possible, an existing authenticated session is required (PR:L), and high attack complexity substantially reduces exploitation reliability. … 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 security update from Microsoft via Windows Update, Windows Server Update Services (WSUS), or the Microsoft Update Catalog, targeting the fixed build for each respective OS version - for example, 10.0.26100.9168 for Windows 11 24H2, 10.0.19045.7663 for Windows 10 22H2, 10.0.20348.5499 for Windows Server 2022, and 10.0.26100.33296 for Windows Server 2025. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all systems running Windows 10, 11, Server 2016, Server 2019, Server 2022, or Server 2025 and verify their current patch level. …
