## Overview

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

devlink: fix possible use-after-free and memory leaks in devlink_init()

The pernet operations structure for the subsystem must be registered
before registering the generic netlink family.

Make an unregister in case of unsuccessful registration.

## Affected

- `linux_kernel >= 6.3, < 6.6.19`
- `linux_kernel >= 6.7, < 6.7.7`
- `linux_kernel = 6.8`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.7.7`
