Details

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.

Severity ?
4.6 (Medium)
CVSS:3.1/AV:P/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
