# Windows VMSwitch out-of-bounds read lets an administrator-level local user escalate privileges (Hyper-V)

Link for people: https://infrastack.ai/live/CVE-2026-97002 (this .md is for agents)

Out-of-bounds read (CWE-125) in the Windows Hyper-V virtual switch driver (VMSwitch). Microsoft's CVSS 7.5 vector is local, high complexity, high privileges required, scope changed. Not known to be exploited; no public PoC found. Microsoft's own page (MSRC) could not be fetched, so build numbers come from a secondary site mirroring the CVE record.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- microsoft:Windows 10 1809 affected >=10.0.17763.0, <10.0.17763.9487 fixed 10.0.17763.9487
- microsoft:Windows 10 21H2 affected >=10.0.19044.0, <10.0.19044.7846 fixed 10.0.19044.7846
- microsoft:Windows 10 22H2 affected >=10.0.19045.0, <10.0.19045.7846 fixed 10.0.19045.7846
- microsoft:Windows 11 23H2 affected >=10.0.22631.0, <10.0.22631.7711 fixed 10.0.22631.7711
- microsoft:Windows 11 24H2 affected >=10.0.26100.0, <10.0.26100.9974 fixed 10.0.26100.9974

## How to check

Run winver or [System.Environment]::OSVersion in PowerShell and compare the build with the fixed builds below; Get-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V shows whether Hyper-V is on. Unconfirmed against MSRC; the list of affected products seen was truncated (+7 more), so check MSRC for Server SKUs.

## Fix

Install the November 2026 Microsoft cumulative update. Fixed builds per secondary source: Win10 1809 10.0.17763.9487; Win10 21H2 10.0.19044.7846; Win10 22H2 10.0.19045.7846; Win11 23H2 10.0.22631.7711; Win11 24H2 10.0.26100.9974. Not verified on MSRC.
