*** This bug is a security vulnerability ***

Public security bug reported:

It was discovered that the Linux kernel failed to take a reference to
the usb_hub structure or to lock the hub interface while initializing
USB hubs. As a result, if a hub is plugged in and quickly unplugged
before the work routine can run, the routine will try to access memory
that has been deallocated. Or, if the hub is unplugged while the routine
is running, the memory may be deallocated while it is in active use.
