## Overview

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

cpufreq: exit() callback is optional

The exit() callback is optional and shouldn't be called without checking
a valid pointer first.

Also, we must clear freq_table pointer even if the exit() callback isn't
present.

## Affected

- `linux_kernel >= 5.1, < 5.4.278`
- `linux_kernel >= 5.5, < 5.10.219`
- `linux_kernel >= 5.11, < 5.15.161`
- `linux_kernel >= 5.16, < 6.1.93`
- `linux_kernel >= 6.2, < 6.6.33`
- `linux_kernel >= 6.7, < 6.8.12`
- `linux_kernel >= 6.9, < 6.9.3`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.9.3`
