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

usb: vhci-hcd: Do not drop references before new references are gained

At a few places the driver carries stale pointers
to references that can still be used. Make sure that does not happen.
This strictly speaking closes ZDI-CAN-22273, though there may be
similar races in the driver.
