      "value": "Azure RTOS USBX is a USB host, device, and on-the-go (OTG) embedded stack. In versions prior to 6.1.10, an attacker can cause a buffer overflow by providing the Azure RTOS USBX host stack a HUB descriptor with `bNbPorts` set to a value greater than `UX_MAX_TT` which defaults to 8. For a `bNbPorts` value of 255, the implementation of `ux_host_class_hub_descriptor_get` function will modify the contents of `hub` -> `ux_host_class_hub_device` -> `ux_device_hub_tt` array violating the end boundary by 255 - `UX_MAX_TT` items. The USB host stack needs to validate the number of ports reported by the hub, and if the value is larger than UX_MAX_TT, USB stack needs to reject the request. This fix has been included in USBX release 6.1.10."

      "value": "Azure RTOS USBX es una pila insertada de host USB, dispositivo y on-the-go (OTG). En versiones anteriores a 6.1.10, un atacante puede causar un desbordamiento del b\u00fafer proporcionando a la pila del host Azure RTOS USBX un descriptor HUB con \"bNbPorts\" establecido en un valor mayor que \"UX_MAX_TT\", que por defecto es 8. Para un valor de \"bNbPorts\" de 255, la implementaci\u00f3n de la funci\u00f3n \"ux_host_class_hub_descriptor_get\" modificar\u00e1 el contenido del array \"hub\" -) \"ux_host_class_hub_device\" -) \"ux_device_hub_tt\" violando el l\u00edmite final en 255 - \"UX_MAX_TT\" elementos. La pila del host USB necesita comprobar el n\u00famero de puertos reportados por el hub, y si el valor es mayor que UX_MAX_TT, la pila USB necesita rechazar la petici\u00f3n. Esta correcci\u00f3n se ha incluido en versi\u00f3n 6.1.10 de USBX"
