Overview

CVE-2026-74565 is a high-severity vulnerability. It was published on August 15, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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

netfilter: nf_tables: make nft_object rhltable per table

The nft_object rhltable is global, this allows for accessing objects

that are being dismangled from lookup path by other existing netns.

Given the nft_obj_destroy() releases the object inmediately, this might

lead to use-after-free of these objects that are being released.

Make the existing rhltable per table to address this issue to deal with

with the nft_rcv_nl_event() path too.

Update nft_obj_lookup() to take the table as non-const, otherwise,

compiler complains when passing the objname_ht to rhltable_lookup().

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
