  - nfc: nfcmrvl: Fix memory leak in nfcmrvl_play_deferred Similar to the handling of play_deferred in commit
    19cfe912c37b (Bluetooth: btusb: Fix memory leak in play_deferred), we thought a patch might be needed
    here as well. Currently usb_submit_urb is called directly to submit deferred tx urbs after unanchor them.
    So the usb_giveback_urb_bh would failed to unref it in usb_unanchor_urb and cause memory leak. Put those
    urbs in tx_anchor to avoid the leak, and also fix the error handling. (CVE-2022-49729)

Note that Nessus relies on the presence of the package as reported by the vendor.");
