Summary
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.
