## Overview

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

netrom: Fix data-races around sysctl_net_busy_read

We need to protect the reader reading the sysctl value because the
value can be changed concurrently.

## Affected

- `linux_kernel >= 2.6.13, < 4.19.310`
- `linux_kernel >= 4.20, < 5.4.272`
- `linux_kernel >= 5.5, < 5.10.213`
- `linux_kernel >= 5.11, < 5.15.152`
- `linux_kernel >= 5.16, < 6.1.82`
- `linux_kernel >= 6.2, < 6.6.22`
- `linux_kernel >= 6.7, < 6.7.10`
- `linux_kernel = 2.6.12`
- `linux_kernel = 6.8`
- `debian_linux = 10.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.7.10`
