# Windows: print workflow service use-after-free lets a local user gain privileges

Link for people: https://infrastack.ai/live/CVE-2026-119928 (this .md is for agents)

A use-after-free bug in the Windows PrintWorkflowUserSvc service lets an attacker who already has a local account raise their privileges. The sources give no more detail on the trigger or the exact affected Windows builds.

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

## Affected

- vendor:Windows 10/11 and Windows Server (PrintWorkflowUserSvc) affected 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; Win11 25H2 < 10.0.26200.9974; Win11 26H1 < 10.0.28000.3501; Win11 26H2 < 10.0.26300.9974; Server 2019 < 10.0.17763.9487; Server 2022 < 10.0.20348.5870; Server 2025 < 10.0.26100.33822 fixed 10.0.17763.9487, 10.0.19044.7846, 10.0.19045.7846, 10.0.22631.7711, 10.0.26100.9974, 10.0.26200.9974, 10.0.28000.3501, 10.0.26300.9974, 10.0.20348.5870, 10.0.26100.33822

## How to check

Run winver or [System.Environment]::OSVersion / (Get-ItemProperty 'HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion').UBR and compare the build number with the fixed builds listed; any lower build is affected. Confirm against the MSRC entry for CVE-2026-119928.

## Fix

Install the November 2026 Windows cumulative update that raises the build to at least: Win10 1809/Server 2019 10.0.17763.9487; Win10 21H2/22H2 10.0.19044.7846 / 10.0.19045.7846; Win11 23H2 10.0.22631.7711; Win11 24H2 10.0.26100.9974; Win11 25H2 10.0.26200.9974; Win11 26H1 10.0.28000.3501; Win11 26H2 10.0.26300.9974; Server 2022 10.0.20348.5870; Server 2025 10.0.26100.33822.
