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.
