## Overview

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

netfilter: nf_tables: disallow anonymous set with timeout flag

Anonymous sets are never used with timeout from userspace, reject this.
Exception to this rule is NFT_SET_EVAL to ensure legacy meters still work.

## Affected

- `linux_kernel >= 4.1, < 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, < 6.1.84`
- `linux_kernel >= 6.2, < 6.6.24`
- `linux_kernel >= 6.7, < 6.7.12`
- `debian_linux = 10.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.7.12`
