CVE-2026-43024

netfilter: nf_tables: reject immediate NF_QUEUE verdict

State: Published
Severity: Not scored
Published: May 1, 2026
Updated: Oct 15, 2026
Reserved: May 1, 2026

Description

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

netfilter: nf_tables: reject immediate NF_QUEUE verdict

nft_queue is always used from userspace nftables to deliver the NF_QUEUE verdict. Immediately emitting an NF_QUEUE verdict is never used by the userspace nft tools, so reject immediate NF_QUEUE verdicts.

The arp family does not provide queue support, but such an immediate verdict is still reachable. Globally reject NF_QUEUE immediate verdicts to address this issue.
