Summary
In the Linux kernel, the following vulnerability has been resolved: wifi: cfg80211: undo netns switch if renaming the wiphy fails Once all the interfaces have been moved, cfg80211_switch_netns() moves the wiphy itself by setting its network namespace and then renaming it, which makes sysfs move it. The rename can fail (but only on allocation failures), leaving things mixed up and hitting the warning there. Ignoring it isn't great, undo the move and let the change fail in this case. If undo fails then WARN, then things would again be stuck in two different network namespaces.
