## Overview

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

net: core: reject skb_copy(_expand) for fraglist GSO skbs

SKB_GSO_FRAGLIST skbs must not be linearized, otherwise they become
invalid. Return NULL if such an skb is passed to skb_copy or
skb_copy_expand, in order to prevent a crash on a potential later
call to skb_gso_segment.

## Affected

- `linux_kernel >= 5.6, < 5.10.217`
- `linux_kernel >= 5.11, < 5.15.159`
- `linux_kernel >= 5.16, < 6.1.91`
- `linux_kernel >= 6.2, < 6.6.31`
- `linux_kernel >= 6.7, < 6.8.10`
- `linux_kernel = 6.9`
- `debian_linux = 10.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.8.10`
