In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: iso: Always release hdev at the end of iso_listen_bis

Since hci_get_route holds the device before returning, the hdev
should be released with hci_dev_put at the end of iso_listen_bis
even if the function returns with an error.
