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.
