## Overview

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

nbd: null check for nla_nest_start

nla_nest_start() may fail and return NULL. Insert a check and set errno
based on other call sites within the same source code.

## Affected

- `linux_kernel >= 4.12, < 5.4.273`
- `linux_kernel >= 5.5, < 5.10.214`
- `linux_kernel >= 5.11, < 5.15.153`
- `linux_kernel >= 5.16, < 6.1.83`
- `linux_kernel >= 6.2, < 6.6.23`
- `linux_kernel >= 6.7, < 6.7.11`
- `linux_kernel >= 6.8, < 6.8.2`
- `debian_linux = 10.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.8.2`
