CVE-2026-98424

wifi: cfg80211: undo netns switch if renaming the wiphy fails

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.
