Severity CVSS v4.0:
Pending analysis

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> netfilter: nf_tables: reject immediate NF_QUEUE verdict<br /> <br /> nft_queue is always used from userspace nftables to deliver the NF_QUEUE<br /> verdict. Immediately emitting an NF_QUEUE verdict is never used by the<br /> userspace nft tools, so reject immediate NF_QUEUE verdicts.<br /> <br /> The arp family does not provide queue support, but such an immediate<br /> verdict is still reachable. Globally reject NF_QUEUE immediate verdicts<br /> to address this issue.
