# Windows Kernel Transaction Manager: use-after-free lets a local user gain higher privileges

Link for people: https://infrastack.ai/live/CVE-2026-119397 (this .md is for agents)

A use-after-free bug in the Kernel Transaction Manager lets an already-authorized local user corrupt kernel memory. An attacker can use it to elevate their privileges on the machine.

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

## How to check

Windows only (not Linux). Check the installed build against the November 2026 Microsoft cumulative update for your Windows version (Settings > Windows Update > Update history, or PowerShell: Get-HotFix). If the November 10 2026 security update is not installed, you are exposed. Exact KB numbers/builds not read from Microsoft's page: look up CVE-2026-119397 in the MSRC Update Guide.

## Fix

Install the November 2026 (Patch Tuesday, 10 Nov) Windows security update for your version. Exact KB/build numbers unknown: MSRC page could not be read.

- 2026-11-10T22:54:23+00:00 analyst https://cvefeed.io/vuln/detail/CVE-2026-119397 — Component is the Windows KTM (CNA is Microsoft, per cvefeed mirror); the earlier 'linux-or-windows' tag was wrong. MSRC and NVD pages not readable via web-cli; no primary doc, so nothing verified, no KB or exact builds. No exploitation reported (ZDI Nov 2026 review list not checked for this CVE).
