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

net: usb: catc: enable basic endpoint checking

catc_probe() fills three URBs with hardcoded endpoint pipes without
verifying the endpoint descriptors:

  - usb_sndbulkpipe(usbdev, 1) and usb_rcvbulkpipe(usbdev, 1) for TX/RX
  - usb_rcvintpipe(usbdev, 2) for interrupt status

A malformed USB device can present these endpoints with transfer types
that differ from what the driver assumes.

Add a catc_usb_ep enum for endpoint numbers, replacing magic constants
throughout. Add usb_check_bulk_endpoints() and usb_check_int_endpoints()
calls after usb_set_interface() to verify endpoint types before use,
rejecting devices with mismatched descriptors at probe time.

Similar to
- commit 90b7f2961798 ("net: usb: rtl8150: enable basic endpoint checking")
which fixed the issue in rtl8150.
