Summary
usb: xhci: Check endpoint is valid before dereferencing it
Details

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

usb: xhci: Check endpoint is valid before dereferencing it

When the host controller is not responding, all URBs queued to all endpoints need to be killed. This can cause a kernel panic if we dereference an invalid endpoint.

Fix this by using xhcigetvirt_ep() helper to find the endpoint and checking if the endpoint is valid before dereferencing it.
