Greg Kroah-Hartman c4e5ae6db2 usb: gadget: renesas_usb3: validate endpoint index in standard request handlers 
commit f880aac8a5 upstream.

The GET_STATUS and SET/CLEAR_FEATURE handlers extract the endpoint
number from the host-supplied wIndex without any sort of validation.
Fix this up by validating the number of endpoints actually match up with
the number the device has before attempting to dereference a pointer
based on this math.

This is just like what was done in commit ee0d382feb ("usb: gadget:
aspeed_udc: validate endpoint index for ast udc") for the aspeed driver.

Fixes: 746bfe63bb ("usb: gadget: renesas_usb3: add support for Renesas USB3.0 peripheral controller")

README 

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
