Overview

CVE-2022-50213 is a high-severity vulnerability. It was published on June 18, 2025 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: do not allow SET_ID to refer to another table

When doing lookups for sets on the same batch by using its ID, a set from a

different table can be used.

Then, when the table is removed, a reference to the set may be kept after

the set is freed, leading to a potential use-after-free.

When looking for sets by ID, use the table that was used for the lookup by

name, and only return sets belonging to that same table.

This fixes CVE-2022-2586, also reported as ZDI-CAN-17470.

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.
