Vulnerability from github – Published: 2026-05-01 15:30 – Updated: 2026-05-01 15:30

Details

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.
