Hi Shuah,

Thanks a lot for the quick fixes.

Please, use this email address: vuln@...unia.com

We have assigned the following CVEs to the issues:
CVE-2017-16911 usbip: prevent vhci_hcd driver from leaking a socket pointer
address
CVE-2017-16912 usbip: fix stub_rx: get_pipe() to validate endpoint number
CVE-2017-16913 usbip: fix stub_rx: harden CMD_SUBMIT path to handle
malicious input
CVE-2017-16914 usbip: fix stub_send_ret_submit() vulnerability to null
transfer_buffer

Please, let me know if we should proceed with a coordinated disclosure. I'm
not quite sure how many distros / downstreams actually use this
functionality.

Best Regards,
Jakub
