# Windows USB driver heap overflow lets a local user gain higher privileges

Link for people: https://infrastack.ai/live/CVE-2026-96057 (this .md is for agents)

Microsoft's CVE record (published 2026-11-10) describes a heap-based buffer overflow (CWE-122) in the Windows USB Driver that lets an authorized local attacker elevate privileges. CVSS 3.1 7.8 (AV:L/PR:L/UI:N), exploit code maturity 'unproven' in the vector. No exploitation or public PoC found. The KB article names are not in the record I could read; the MSRC page itself did not load.

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

## Affected

- vendor:windows-10 affected 1607 < 10.0.14393.9688; 1809 < 10.0.17763.9487; 21H2 < 10.0.19044.7846; 22H2 < 10.0.19045.7846 fixed 10.0.14393.9688, 10.0.17763.9487, 10.0.19044.7846, 10.0.19045.7846

- vendor:windows-server affected 2016 < 10.0.14393.9688; 2019 < 10.0.17763.9487; 2022 < 10.0.20348.5870; 2025 < 10.0.26100.33822 fixed 10.0.14393.9688, 10.0.17763.9487, 10.0.20348.5870, 10.0.26100.33822

## How to check

Get the build with winver, or (Get-ComputerInfo).OsBuildNumber plus UBR (reg query 'HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion' /v UBR), and compare to the fixed build for your release: 1607/Server 2016 10.0.14393.9688; 1809/Server 2019 10.0.17763.9487; 21H2 10.0.19044.7846; 22H2 10.0.19045.7846; Server 2022 10.0.20348.5870; 23H2 10.0.22631.7711; 24H2 10.0.26100.9974; 25H2 10.0.26200.9974; 26H2 10.0.26300.9974; Server 2025 10.0.26100.33822; 26H1 10.0.28000.3501. Below that = exposed.

## Fix

Install the November 2026 Windows cumulative update that brings your release to the build listed above or later. KB number not confirmed.

- 2026-11-10T19:58:25+00:00 analyst https://cveawg.mitre.org/api/cve/CVE-2026-96057 — Microsoft CNA CVE record (cveawg) gives affected/fixed builds; MSRC update guide page did not load so KB names unknown. No exploitation or PoC seen; social search skipped. No check written: build comparison needs host state, not repo files.
