Overview
About vulnerability
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.
