## Overview

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

netfilter: nf_tables: Fix potential data-race in __nft_flowtable_type_get()

nft_unregister_flowtable_type() within nf_flow_inet_module_exit() can
concurrent with __nft_flowtable_type_get() within nf_tables_newflowtable().
And thhere is not any protection when iterate over nf_tables_flowtables
list in __nft_flowtable_type_get(). Therefore, there is pertential
data-race of nf_tables_flowtables list entry.

Use list_for_each_entry_rcu() to iterate over nf_tables_flowtables list
in __nft_flowtable_type_get(), and use rcu_read_lock() in the caller
nft_flowtable_type_get() to protect the entire type query process.

## Affected

- `linux_kernel >= 4.16, < 4.19.312`
- `linux_kernel >= 4.20, < 5.4.274`
- `linux_kernel >= 5.5, < 5.10.215`
- `linux_kernel >= 5.11, < 5.15.154`
- `linux_kernel >= 5.16, < 6.1.85`
- `linux_kernel >= 6.2, < 6.6.26`
- `linux_kernel >= 6.7, < 6.8.5`
- `linux_kernel = 6.9`
- `debian_linux = 10.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.8.5`
