"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nBluetooth: ISO: release unused CIS holds after channel attach\n\nhci_bind_cis() and hci_connect_cis() return one hci_conn hold for the\nISO layer. A new channel association consumes that hold, which is\neventually released by iso_conn_free().\n\nThere are two cases where iso_chan_add() does not create an association:\nit returns success when the socket is already attached to the same\niso_conn, and it returns -EBUSY when another socket is attached. The\nhold returned for the current call is unused in both cases. This occurs\nwhen deferred setup calls iso_connect_cis() again for its existing\nsocket, or when another socket attempts to reuse the CIS.\n\nDetect the idempotent case while the connection is locked and release\nthe unused hold after iso_chan_add(). Also release it on -EBUSY. Do not\ndrop it for other errors: a newly allocated iso_conn releases the\ntransferred hold when its last temporary reference is put."
