Details

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

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

The "openinfo" variable is added to the &vmbusconnection.chnmsglist, 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.
