    "description": "In the Linux kernel, the following vulnerability has been resolved:\n\nbatman-adv: bla: prevent use-after-free when deleting claims\n\nWhen batadv_bla_del_backbone_claims() removes all claims for a backbone, it\ndoes this by dropping the link entry in the hash list. This list entry\nitself was one of the references which need to be dropped at the same time\nvia batadv_claim_put().\n\nBut the batadv_claim_put() must not be done before the last access to the\nclaim object in this function. Otherwise the claim might be freed already\nby the batadv_claim_release() function before the list entry was dropped.",
