  "details": "In the Linux kernel, the following vulnerability has been resolved:  batman-adv: v: prevent OGM aggregation on disabled hardif  When an interface gets disabled, the worker is correctly disabled by batadv_hardif_disable_interface() -\u003e ... -\u003e batadv_v_ogm_iface_disable(). In this process, the skb aggr_list is also freed.  But batadv_v_ogm_send_meshif() can still queue new skbs (via batadv_v_ogm_queue_on_if()) to the aggr_list. This will only stop after all cores can no longer find the RCU protected list of hard interfaces. These queued skbs will never be freed or consumed by batadv_v_ogm_aggr_work.  The batadv_v_ogm_iface_disable() function must block batadv_v_ogm_queue_on_if() to avoid leak of skbs.",
