## Overview

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

netfilter: bridge: eb_tables: close module init race

sashiko reports for unrelated patch:
 Does the core ebtables initialization in ebtables.c suffer from a similar race?
 Once nf_register_sockopt() completes, the sockopts are exposed globally.

sockopt has to be registered last, just like in ip/ip6/arptables.

## Affected

- `linux_kernel >= 5.13, < 6.18.34`
- `linux_kernel >= 6.19, < 7.0.11`
- `linux_kernel = 7.1`

## Remediation

Upgrade past the affected range:

- `linux_kernel 7.0.11`
