## Overview

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

ethtool: module: call ethnl_ops_complete() on module flash errors

When validate() fails we are skipping over ethnl_ops_complete()
even tho we already called ethnl_ops_begin().

## Affected

- `linux_kernel >= 6.11, < 6.18.35`
- `linux_kernel >= 6.19, < 7.0.12`
- `linux_kernel = 7.1`

## Remediation

Upgrade past the affected range:

- `linux_kernel 7.0.12`
