## Overview

A flaw was found in the Linux kernel's `sensorhub` component. A local attacker could provide a maliciously crafted sensor number in an EC FIFO event. This unchecked sensor number could lead to an out-of-bounds read and write in the `batch_state` array, potentially causing memory corruption or system instability.
