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

Link for people: https://infrastack.ai/live/CVE-2026-96117 (this .md is for agents)

A heap-based buffer overflow in the Windows LUAFV driver, which handles file virtualization for legacy applications, lets an authorized local user elevate privileges. An attacker who already has a logon on the machine can gain system-level control.

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

- 2026-11-10T19:47:22+00:00 analyst — NVD and cve.org pages for CVE-2026-96117 return no description, versions or KB, and MSRC has no indexed page. Searches found no source for this ID. A sibling, CVE-2026-50472 (published 2026-08-11), has the same LUAFV heap overflow wording, CVSS 7.0 AV:L/AC:H/PR:L, and is not in KEV. I did not copy its versions here because the ID is not confirmed to be the same record. Possibly a mistyped or reserved ID, or a duplicate of 50472; code decides merges. Settled by the MSRC update-guide entry for this exact ID. Nothing verified.

## From the sources

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