CVE-2026-43024

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the netfilter nf tables component where immediate NF QUEUE verdicts could be emitted. While nft queue is intended for userspace nftables to deliver verdicts, immediate emission is not used by userspace nft tools. This is particularly relevant for the arp family, which lacks queue support but could still reach an immediate verdict.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
