Description

HID: intel-ish-hid: Fix use-after-free issue in ishtp_hid_remove()

In the Linux kernel, the following vulnerability has been resolved:

HID: intel-ish-hid: Fix use-after-free issue in ishtp_hid_remove()

The system can experience a random crash a few minutes after the driver is

removed. This issue occurs due to improper handling of memory freeing in

the ishtp_hid_remove() function.

The function currently frees the driver_data directly within the loop

that destroys the HID devices, which can lead to accessing freed memory.

Specifically, hid_destroy_device() uses driver_data when it calls

hid_ishtp_set_feature() to power off the sensor, so freeing

driver_data beforehand can result in accessing invalid memory.

This patch resolves the issue by storing the driver_data in a temporary

variable before calling hid_destroy_device(), and then freeing the

driver_data after the device is destroyed.

How this vulnerability can be exploited

This issue can be reached with local access to the system, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity high, availability high.
