## Overview

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

netfilter: nf_tables: fully validate NFT_DATA_VALUE on store to data registers

register store validation for NFT_DATA_VALUE is conditional, however,
the datatype is always either NFT_DATA_VALUE or NFT_DATA_VERDICT. This
only requires a new helper function to infer the register type from the
set datatype so this conditional check can be removed. Otherwise,
pointer to chain object can be leaked through the registers.

## Affected

- `linux_kernel < 3.13`
- `linux_kernel >= 3.14, < 4.19.317`
- `linux_kernel >= 4.20, < 5.4.279`
- `linux_kernel >= 5.5, < 5.10.221`
- `linux_kernel >= 5.11, < 5.15.162`
- `linux_kernel >= 5.16, < 6.1.97`
- `linux_kernel >= 6.2, < 6.6.37`
- `linux_kernel >= 6.7, < 6.9.8`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.9.8`
