## Overview

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

netfilter: nft_set_pipapo: release elements in clone only from destroy path

Clone already always provides a current view of the lookup table, use it
to destroy the set, otherwise it is possible to destroy elements twice.

This fix requires:

 212ed75dc5fb ("netfilter: nf_tables: integrate pipapo into commit protocol")

which came after:

 9827a0e6e23b ("netfilter: nft_set_pipapo: release elements in clone from abort path").

## Affected

- `linux_kernel >= 5.10.130, < 5.10.214`
- `linux_kernel >= 5.15.54, < 5.15.153`
- `linux_kernel >= 5.18.11, < 6.1.83`
- `linux_kernel >= 6.2, < 6.6.23`
- `linux_kernel >= 6.7, < 6.7.11`
- `linux_kernel >= 6.8, < 6.8.2`
- `debian_linux = 10.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.8.2`
