CVE-2024-42226

In the Linux kernel, the following vulnerability has been resolved: usb: xhci: prevent potential failure in handle_tx_event() for Transfer events without TRB Some transfer events don’t always point to a TRB, and consequently don’t have a endpoint ring. In these cases, function handle_tx_event() should not proceed, because if ‘ep->skip’ is set, the pointer to the endpoint ring is used. To prevent a potential failure and make the code logical, return after checking the completion code for a Transfer event without TRBs.
