      "value": "Issuing an ICMP ping via the `net ping` shell command to a device's own IPv4 address causes the network stack to recursively re-enter the input path on the same system work-queue stack. Because the destination is recognized as a local address, both the echo request and the resulting echo reply are processed inline before the current frame returns. The nested input-path frames exceed the work-queue stack and trigger a stack overflow."

    {
      "lang": "es",
      "value": "Emitir un ping ICMP a través del comando de shell ’net ping’ a la propia dirección IPv4 de un dispositivo provoca que la pila de red reingrese recursivamente la ruta de entrada en la misma pila de cola de trabajo del sistema. Debido a que el destino se reconoce como una dirección local, tanto la solicitud de eco como la respuesta de eco resultante se procesan en línea antes de que el marco actual regrese. Los marcos de ruta de entrada anidados exceden la pila de cola de trabajo y desencadenan un desbordamiento de pila."
