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.
