  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nusb: gadget: renesas_usb3: validate endpoint index in standard request handlers\n\nThe GET_STATUS and SET/CLEAR_FEATURE handlers extract the endpoint\nnumber from the host-supplied wIndex without any sort of validation.\nFix this up by validating the number of endpoints actually match up with\nthe number the device has before attempting to dereference a pointer\nbased on this math.\n\nThis is just like what was done in commit ee0d382feb44 (\"usb: gadget:\naspeed_udc: validate endpoint index for ast udc\") for the aspeed driver.",
