# Windows OLE: heap buffer overflow lets a local user gain higher privileges

Link for people: https://infrastack.ai/live/CVE-2026-95933 (this .md is for agents)

A heap-based buffer overflow in Windows OLE lets an attacker who already has a local account raise their privileges. The sources describe no remote trigger and no public exploit.

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

## How to check

- Open the Microsoft Security Update Guide entry for CVE-2026-95933 (msrc.microsoft.com/update-guide), find your Windows version in the Security Updates table and note the KB number.
- Run 'winver' for your build, or 'Get-HotFix -Id KB<number>' in PowerShell, to see whether that KB is installed. Affected builds and the KB are unknown until the MSRC page is read.

## Timeline

- 2026-11-10T19:25:24+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-95933
- 2026-11-10T20:24:04+00:00 analyst — Could not read the MSRC Update Guide entry (JavaScript-only, web-cli returned empty) and NVD/cve.org pages are empty or have no build list. No primary source linked, so nothing verified. Affected builds, patch KB and fix are unknown. A browser-cli read of the MSRC page would settle them. Fix status 'none' on the record is not backed by a vendor page.

## From the sources

Heap-based buffer overflow in Windows OLE allows an authorized attacker to elevate privileges locally.
