# Windows Text Services Framework: out-of-bounds read lets local users gain privileges

Link for people: https://infrastack.ai/live/CVE-2026-119925 (this .md is for agents)

Windows Text Services Framework reads memory past the end of a buffer when handling input. An authorized local user can use this to raise their privileges on the machine.

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

## How to check

- Run winver (or: cmd /c ver) and compare the build with the fixed build in the MSRC Update Guide entry for CVE-2026-119925
- Confirm the November 2026 (2026-11) cumulative update is installed: Settings > Windows Update > Update history
- Affected builds and KB numbers: unknown, not read from a primary page

## Fix

Install the November 2026 Windows cumulative update (MSRC lists the CVE in the 2026-Nov release). The exact KB and fixed build numbers are unknown; the MSRC update guide entry for this CVE would settle it.

## Timeline

- 2026-11-10T19:25:03+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-119925
- 2026-11-10T22:22:01+00:00 analyst https://api.msrc.microsoft.com/cvrf/v3.0/updates/CVE-2026-119925 — MSRC API confirms the CVE is in the Nov 2026 Security Updates, but the update-guide page was not retrievable and the CVRF file is too large for the tools, so builds and KBs are unknown. Nothing verified. Fix-status was none in the record with no vendor page saying so; set to unknown. Search for chatter not run.

## Documents

- [advisory] MSRC update index: CVE-2026-119925 is in November 2026 Security Updates https://api.msrc.microsoft.com/cvrf/v3.0/updates/CVE-2026-119925

## From the sources

Out-of-bounds read in Windows Text Services Framework allows an authorized attacker to elevate privileges locally.
