Official 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.

Technical Analysis

CVE-2026-46125 requires adjacent network access, limiting remote exploitation but still posing risk in shared or local network environments.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 8.8.
