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.
