title: uio_hv_generic: Fix a memory leak in error handling paths
description: In the Linux kernel, the following vulnerability has been resolved:
uio_hv_generic: Fix a memory leak in error handling paths
If 'vmbus_establish_gpadl()' fails, the (recv|send)_gpadl will not be
updated and 'hv_uio_cleanup()' in the error handling path will not be
able to free the corresponding buffer.
In such a case, we need to free the buffer explicitly.
