## Overview

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

wifi: iwlwifi: mei: pass correct argument to function

The first argument to iwl_mei_write_cyclic_buf() should be the cldev
but the q_head pointer is passed instead. Fix it.

## Affected

- `linux_kernel >= 5.17, < 6.1.188`
- `linux_kernel >= 6.2, < 6.6.157`
- `linux_kernel >= 6.7, < 6.12.110`
- `linux_kernel >= 6.13, < 6.18.52`
- `linux_kernel >= 6.19, < 7.2.6`

## Remediation

Upgrade past the affected range:

- `linux_kernel 7.2.6`
