## Overview

A vulnerability was found in the Linux kernel's nft_set_desc_concat_parse() function .This flaw allows an attacker to trigger a buffer overflow via nft_set_desc_concat_parse() , causing a denial of service and possibly to run code.

## Affected

- `linux_kernel < 5.19`
- `virtualization = 4.0`
- `enterprise_linux = 8.0`
- `enterprise_linux = 9.0`
- `debian_linux = 11.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 5.19`
