Overview

CVE-2026-46125 is a high-severity vulnerability. It was published on May 28, 2026 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

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

wifi: mac80211: remove station if connection prep fails

If connection preparation fails for MLO connections, then the

interface is completely reset to non-MLD. In this case, we must

not keep the station since it's related to the link of the vif

being removed. Delete an existing station. Any "new_sta" is

already being removed, so that doesn't need changes.

This fixes a use-after-free/double-free in debugfs if that's

enabled, because a vif going from MLD (and to MLD, but that's

not relevant here) recreates its entire debugfs.

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.
