## Overview

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

net: ice: Fix potential NULL pointer dereference in ice_bridge_setlink()

The function ice_bridge_setlink() may encounter a NULL pointer dereference
if nlmsg_find_attr() returns NULL and br_spec is dereferenced subsequently
in nla_for_each_nested(). To address this issue, add a check to ensure that
br_spec is not NULL before proceeding with the nested attribute iteration.

## Affected

- `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 = 6.8`
- `debian_linux = 10.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.7.10`
