# Windows: stack buffer overflow lets a signed-in user gain system rights

Link for people: https://infrastack.ai/live/CVE-2026-105493 (this .md is for agents)

A stack-based buffer overflow in the Windows Advanced Rasterization Platform lets a local attacker who already has an account raise their privileges. The flaw is local only and the sources give no evidence of exploitation in the wild.

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