| Description | 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. |
