Overview

CVE-2023-53179 is a high-severity vulnerability. It was published on September 15, 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: ipset: add the missing IP_SET_HASH_WITH_NET0 macro for ip_set_hash_netportnet.c

The missing IP_SET_HASH_WITH_NET0 macro in ip_set_hash_netportnet can

lead to the use of wrong `CIDR_POS(c)` for calculating array offsets,

which can lead to integer underflow. As a result, it leads to slab

out-of-bound access.

This patch adds back the IP_SET_HASH_WITH_NET0 macro to

ip_set_hash_netportnet to address the issue.

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.
