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