## Overview

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

netfilter: nft_payload: sanitize offset and length before calling skb_checksum()

If access to offset + length is larger than the skbuff length, then
skb_checksum() triggers BUG_ON().

skb_checksum() internally subtracts the length parameter while iterating
over skbuff, BUG_ON(len) at the end of it checks that the expected
length to be included in the checksum calculation is fully consumed.

## Affected

- `linux_kernel >= 4.5, < 4.19.323`
- `linux_kernel >= 4.20, < 5.4.285`
- `linux_kernel >= 5.5, < 5.10.229`
- `linux_kernel >= 5.11, < 5.15.171`
- `linux_kernel >= 5.16, < 6.1.116`
- `linux_kernel >= 6.2, < 6.6.60`
- `linux_kernel >= 6.7, < 6.11.7`
- `linux_kernel = 6.12`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.11.7`
