# Windows Win32K: uninitialized memory lets a local user read data

Link for people: https://infrastack.ai/live/CVE-2026-95893 (this .md is for agents)

Windows Win32K, the kernel graphics driver, reads a resource it never initialized, which can leak memory contents. An attacker who already has a logon on the machine can read information they should not see.

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

## How to check

- Check the Windows build with `winver` and compare it against the Microsoft security update guide entry for CVE-2026-95893
- Confirm Windows Update has installed the latest cumulative update
