Untrusted pointer dereference in Windows Hyper-V allows an authorized attacker to execute code locally.
AnalysisAI
Guest-to-host code execution in Windows Hyper-V affects authorized guest VM users who can trigger an untrusted pointer dereference (CWE-822) to execute code in the hypervisor context, effectively escaping the VM sandbox. The CVSS scope-change metric (S:C) confirms this is a privilege escalation from guest to host, making it a hypervisor escape with full High C/I/A impact on the underlying host. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authorized (authenticated) user account within a running Hyper-V guest VM on an affected Windows Server 2022/2025 or Windows 11 (23H2-25H2) host. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 8.8 with S:C (scope change) accurately reflects the severity of a VM escape primitive: a low-privileged guest user with local access can achieve full Host C:H/I:H/A:H impact. … 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 via Windows Update or WSUS. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Windows Server 2022, Windows Server 2025, and Windows 11 (versions 23H2-25H2) systems with Hyper-V enabled and assess scope of exposure based on guest VM trust models and privilege access. …
