## Overview

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

bpf: Fix a segment issue when downgrading gso_size

Linearize the skb when downgrading gso_size because it may trigger a
BUG_ON() later when the skb is segmented as described in [1,2].

## Affected

- `linux_kernel >= 4.13, < 5.4.282`
- `linux_kernel >= 5.5, < 5.10.224`
- `linux_kernel >= 5.11, < 5.15.165`
- `linux_kernel >= 5.16, < 6.1.103`
- `linux_kernel >= 6.2, < 6.6.44`
- `linux_kernel >= 6.7, < 6.10.3`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.10.3`
