CVE-2026-52926

batman-adv: clear current gateway during teardown

State: Published
Severity: Not scored
Published: Jun 24, 2026

Reserved: Jun 9, 2026

Description

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.
