## Overview

A flaw was found in the Linux kernel's Human Interface Device (HID) sensor custom driver. When creating sysfs groups for custom sensor fields, the `hid_sensor_custom_add_attributes()` function fails to properly clean up previously created groups if an error occurs. This improper resource management could lead to system instability or a denial of service (DoS) condition.
