# Wi-Fi NPU firmware: out-of-bounds write can crash the device locally

Link for people: https://infrastack.ai/live/CVE-2026-89142 (this .md is for agents)

The Wi-Fi NPU firmware has a bounds check that is wrong, allowing an out-of-bounds write. A local user with execution privileges can trigger a denial of service.

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

## From the sources

In the Wi-Fi NPU FW, there is a possible out-of-bounds write due to an incorrect bounds check. This could lead to local denial of service with user execution privileges needed. User interaction is not needed for exploitation.
