Overview

CVE-2026-23451 is a high-severity vulnerability. It was published on April 3, 2026 and has a CVSS 3.1 base score of 7.5 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

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

bonding: prevent potential infinite loop in bond_header_parse()

bond_header_parse() can loop if a stack of two bonding devices is setup,

because skb->dev always points to the hierarchy top.

Add new "const struct net_device *dev" parameter to

(struct header_ops)->parse() method to make sure the recursion

is bounded, and that the final leaf parse method is called.

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.
