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

Link for people: https://infrastack.ai/live/CVE-2026-96152 (this .md is for agents)

NVD (CVSS 7.8, local, low privileges, no user interaction) lists a stack-based buffer overflow in Windows Installer that lets an authorized local attacker elevate privileges. No Microsoft page with affected builds, KB or fix could be read; no exploitation or public PoC found.

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

## How to check

Unknown until Microsoft lists affected builds. Meanwhile, check the Windows build (winver) and installed updates against the MSRC Security Update Guide entry for CVE-2026-96152.

## Timeline

- 2026-11-10T19:25:31+00:00 nvd https://nvd.nist.gov/vuln/detail/CVE-2026-96152
- 2026-11-10T19:45:19+00:00 analyst — Could not read primary source: MSRC advisory page returned nothing (JS-only), NVD page text empty. Affected builds, KB and fix remain unknown; nothing verified. Revisit when MSRC/Patch Tuesday lists it (check Nov 2026 Patch Tuesday).

## From the sources

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