"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet/sched: act_api: release tail references on DELACTION failure\n\nA batched RTM_DELACTION request takes a temporary reference on each\naction before attempting any deletion. tcf_action_delete() clears\neach processed slot and drops its temporary reference before attempting\nthe deletion. If deletion fails, tca_action_gd() calls\ntcf_action_put_many() to release the remaining references, but its\ntcf_act_for_each_action() iterator stops at the first NULL slot.\n\nWhen a batch stops at an action bound to a filter, this leaks a\nreference on each subsequent action. A later delete of an unbound\naction can then return success without removing it from the IDR.\n\nWalk the full array in tcf_action_put_many() and skip NULL slots to\nrelease the references held on the unprocessed actions."
