# Linux kernel Edge TPU driver: use-after-free allows local privilege escalation

Link for people: https://infrastack.ai/live/CVE-2026-59598 (this .md is for agents)

A use-after-free in the Edge TPU driver's watchdog handler (platform_rio_ncp_wdt_handler in edgetpu_rio.c) can be triggered on the device. The description says it can lead to local privilege escalation, which requires execution privileges on the machine.

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

## From the sources

In platform_rio_ncp_wdt_handler of edgetpu_rio.c, there is a possible Use After Free due to a use after free. This could lead to local escalation of privilege with execution privileges needed. User interaction is for exploitation.
