In the Linux kernel, the following vulnerability has been resolved:
uio_hv_generic: Fix another memory leak in error handling paths
Memory allocated by 'vmbus_alloc_ring()' at the beginning of the probe function is never freed in the error handling path.
Add the missing 'vmbus_free_ring()' call.
Note that it is already freed in the .remove function.
