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

Link for people: https://infrastack.ai/live/CVE-2026-96062 (this .md is for agents)

A heap-based buffer overflow in Windows Installer lets an attacker who already has a local account raise their privileges. The sources give no further detail on the trigger or affected builds.

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

## Affected

## How to check

Unknown until Microsoft's Security Update Guide entry for CVE-2026-96062 is readable. Check whether the November 2026 cumulative update for your Windows build is installed (winver or Get-HotFix) and compare it with the KB listed in the MSRC entry.

## Timeline

- 2026-11-10T19:25:29+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-96062
- 2026-11-10T19:57:09+00:00 analyst — MSRC and NVD pages return no content to web-cli (JS-only/empty); no primary page read, so no fix, builds or KB known. Nothing verified. Revisit when MSRC is readable (Nov 2026 Patch Tuesday cumulative updates likely).

## From the sources

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