## Overview

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

HID: multitouch: Correct devm device reference for hidinput input_dev name

Reference the HID device rather than the input device for the devm
allocation of the input_dev name. Referencing the input_dev would lead to a
use-after-free when the input_dev was unregistered and subsequently fires a
uevent that depends on the name. At the point of firing the uevent, the
name would be freed by devres management.

Use devm_kasprintf to simplify the logic for allocating memory and
formatting the input_dev name string.

## Affected

- `linux_kernel >= 3.12, < 4.14.326`
- `linux_kernel >= 4.15, < 4.19.295`
- `linux_kernel >= 4.20, < 5.4.257`
- `linux_kernel >= 5.5, < 5.10.195`
- `linux_kernel >= 5.11, < 5.15.132`
- `linux_kernel >= 5.16, < 6.1.53`
- `linux_kernel >= 6.2, < 6.4.16`
- `linux_kernel >= 6.5, < 6.5.3`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.5.3`
