n the Linux kernel, the following vulnerability has been resolved: can: mcba_usb: mcba_usb_read_bulk_callback(): fix URB memory leak Fix similar memory leak as in commit 7352e1d5932a ("can: gs_usb: gs_usb_receive_bulk_callback(): fix URB memory leak"). In mcba_usb_probe() -> mcba_usb_start(), the URBs for USB-in transfers are allocated, added to the priv->rx_submitted anchor and submitted. In the complete callback mcba_usb_read_bulk_callback(), the URBs are processed and resubmitted. In mcba_usb_close() -> mcba_urb_unlink() the URBs are freed by calling usb_kill_anchored_urbs(&priv->rx_submitted). However, this does not take into account that the USB framework unanchors the URB before the complete function is called. This means that once an in-URB has been completed, it is no longer anchored and is ultimately not released in usb_kill_anchored_urbs(). Fix the memory leak by anchoring the URB in the mcba_usb_read_bulk_callback()to the priv->rx_submitted anchor.
