## Overview

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

HID: roccat: fix use-after-free in roccat_report_event

roccat_report_event() iterates over the device->readers list without
holding the readers_lock. This allows a concurrent roccat_release() to
remove and free a reader while it's still being accessed, leading to a
use-after-free.

Protect the readers list traversal with the readers_lock mutex.

## Affected

- `linux_kernel >= 2.6.35, < 6.6.136`
- `linux_kernel >= 6.7, < 6.12.83`
- `linux_kernel >= 6.13, < 6.18.24`
- `linux_kernel >= 6.19, < 6.19.14`
- `linux_kernel = 7.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.19.14`
