Description
In the Linux kernel, the following vulnerability has been resolved:

Drivers: hv: vmbus: Use after free in __vmbus_open()

The "open_info" variable is added to the &vmbus_connection.chn_msg_list,
but the error handling frees "open_info" without removing it from the
list. This will result in a use after free. First remove it from the
list, and then free it.
