Description
In the Linux kernel, the following vulnerability has been resolved:
usb: xhci: Add error handling in xhci_map_urb_for_dma
Currently xhci_map_urb_for_dma() creates a temporary buffer and copies
the SG list to the new linear buffer. But if the kzalloc_node() fails,
then the following sg_pcopy_to_buffer() can lead to crash since it
tries to memcpy to NULL pointer.
So return -ENOMEM if kzalloc returns null pointer.
