CVE-2026-63834

The CVE concerns the Linux kernel’s batman-adv tp_meter: unacked_list can be pressured to grow (via crafted small messages, seqno gaps) if the list is unbounded. The result is potential out-of-memory or high CPU usage from scanning a large unacked_list. If a limit is applied, the implementation m...

CVE-2026-63835

CVE-2026-63835 concerns the Linux kernel’s batman-adv OGM aggregation on disabled hard interfaces. When an interface is disabled, batadv_hardif_disable_interface() disables the worker and frees the skb aggr_list; however batadv_v_ogm_send_meshif() may still queue new skbs via batadv_v_ogm_queue_o...
