## Overview

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

netfilter: ebtables: move to two-stage removal scheme

Like previous patches for x_tables, follow same pattern in ebtables.
We can't reuse xt helpers: ebt_table struct layout is incompatible.

table->ops assignment is now done while still holding the ebt mutex
to make sure we never expose partially-filled table struct.

## Affected

- `linux_kernel >= 5.15, < 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`
