      "title": "Bluetooth: ISO: balance the parent hold in hci_bind_bis()",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: ISO: balance the parent hold in hci_bind_bis()\n\nhci_conn_link() takes a lifetime reference to its parent with\nhci_conn_get(), but only takes an operational hold on the child.\nhci_conn_unlink() later balances both a hold and a reference on the\nparent.\n\nThe SCO and CIS paths pass a parent acquired from a connect helper, so\nit already has a hold. For an additional BIS, hci_bind_bis() obtains the\nparent from hci_conn_hash_lookup_big(), which returns a bare pointer.\nUnlinking the child then drops the parent's existing hold and can\nschedule it for disconnection while its socket is still using it.\n\nTake a hold on the parent before linking it and drop that hold if linking\nfails. A successful link transfers the hold to hci_conn_unlink().",
