In the Linux kernel, the following vulnerability has been resolved:
usb: core: Add lock to usb_wakeup_notification()
Add a spin lock to usb_wakeup notification to prevent a race condition
with dereferencing freed memory. This could be hit by the xHCI driver as
it calls this function from an IRQ and could race with the
hub_disconnect() function, which properly grabs this lock to protect the
state of the device.
