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

batman-adv: clear current gateway during teardown

batadv gw node free() removes the gateway list entries during mesh teardown, but it does not clear the currently selected gateway. This leaves stale gateway state behind across cleanup and can break a later mesh recreation.

Clear bat priv->gw.curr gw before walking the gateway list so the selected gateway reference is dropped as part of teardown.
