## Overview

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

ipmi:ssif: Clean up kthread on errors

If an error occurs after the ssif kthread is created, but before the
main IPMI code starts the ssif interface, the ssif kthread will not
be stopped.

So make sure the kthread is stopped on an error condition if it is
running.

## Affected

- `linux_kernel >= 3.19, < 5.10.258`
- `linux_kernel >= 5.11, < 5.15.209`
- `linux_kernel >= 5.16, < 6.18.27`
- `linux_kernel >= 6.19, < 7.0.4`

## Remediation

Upgrade past the affected range:

- `linux_kernel 7.0.4`
