In the Linux kernel, the following vulnerability has been resolved:
can: usb: f81604: correctly anchor the urb in the read bulk callback
When submitting an urb, that is using the anchor pattern, it needs to be
anchored before submitting it otherwise it could be leaked if
usb_kill_anchored_urbs() is called. This logic is correctly done
elsewhere in the driver, except in the read bulk callback so do that
here also.
