In the Linux kernel, the following vulnerability has been resolved: nfc: nfcmrvl: Fix memory leak in nfcmrvlplaydeferred Similar to the handling of playdeferred in commit 19cfe912c37b ("Bluetooth: btusb: Fix memory leak in playdeferred"), we thought a patch might be needed here as well. Currently usbsubmiturb is called directly to submit deferred tx urbs after unanchor them. So the usbgivebackurbbh would failed to unref it in usbunanchorurb and cause memory leak. Put those urbs in txanchor to avoid the leak, and also fix the error handling.
