Описание
In the Linux kernel, the following vulnerability has been resolved:
Drivers: hv: vmbus: Fix memory leak in vmbus_add_channel_kobj
kobject_init_and_add() takes reference even when it fails. According to the doc of kobject_init_and_add()：
If this function returns an error, kobject_put() must be called to properly clean up the memory associated with the object.
Fix memory leak by calling kobject_put().
