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

Link for people: https://infrastack.ai/live/CVE-2026-95872 (this .md is for agents)

A heap-based buffer overflow in the Windows USB driver lets an authorized local user elevate their privileges. An attacker who already has a logon on the machine can gain system-level control.
