# Windows Kernel: missing authorization lets a local user gain higher privileges

Link for people: https://infrastack.ai/live/CVE-2026-112802 (this .md is for agents)

Microsoft says a missing authorization check in the Windows kernel lets a local attacker who already has low privileges elevate them (CVSS 3.1 7.8, AV:L/AC:L/PR:L/UI:N). It was published on 2026-11-10 with the November 2026 updates. Affected builds and the fixing update are not yet confirmed from Microsoft's own page.

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

## How to check

Run winver and compare the build with the CVE-2026-112802 entry in Microsoft's Security Update Guide (affected builds not yet confirmed here). Check Windows Update history for the November 2026 cumulative update.

## Timeline

- 2026-11-10T19:24:33+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-112802
- 2026-11-11T00:04:51+00:00 analyst https://nvd.nist.gov/vuln/detail/CVE-2026-112802 — MSRC update guide page is JS-only (web-cli and CVRF API returned nothing usable), so affected builds and fixed KB are not confirmed. NVD (Microsoft as CNA) gives CVSS 7.8, local, low privileges, no user interaction; no exploitation reported, not in KISA/KEV per Rapid7. Nothing marked verified. Needs the MSRC page read in a browser or the November 2026 Patch Tuesday KB list.
