      "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: xilinx: axienet: Poner en cola los paquetes Tx en dql antes de que se inicie dmaengine Poner en cola los paquetes en dql despu\u00e9s de que se inicie el motor dma provoca una condici\u00f3n de ejecuci\u00f3n. La transferencia Tx comienza una vez que se inicia el motor dma y puede ejecutar dql dequeue al finalizar antes de que se ponga en cola. Esto da como resultado el siguiente bloqueo del kernel mientras se ejecuta la prueba de estr\u00e9s iperf: \u00a1ERROR del kernel en lib/dynamic_queue_limits.c:99!
