In the Linux kernel, the following vulnerability has been resolved: batman-adv: bla: put backbone reference on failed claim hash insert When batadv_bla_add_claim() fails to insert a new claim into the hash, it leaked a reference to the backbone_gw for which the claim was intended. Call batadv_backbone_gw_put() on the error path to release the reference and avoid leaking the backbone_gw object.

A flaw was found in the Linux kernel's batman-adv (Better Approach To Mobile Ad-hoc Networking - Advanced) Basic Link Arbitration (BLA) module. When the batadv_bla_add_claim() function fails to insert a new claim into the hash, it leaks a reference to the backbone_gw object. This resource leak can accumulate over time, potentially leading to system instability or a Denial of Service (DoS) condition.
