After\\nconsidering typical scenarios, such as OpenSM processing, which can\\nhandle approximately 100k packets per second, and the 1-second retry\\ntimeout for most packets, we set the list size limit to 200k. Packets\\nreceived beyond this limit are dropped, assuming they are likely timed\\nout by the time they are handled by user-space.\\n\\nNotably, packets queued on the receive list due to reasons like\\ntimed-out sends are preserved even when the list is full.\"},{\"lang\":\"es\",\"value\":\"En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: IB/core: implementar un l\u00edmite en la lista de recepci\u00f3n de UMAD El comportamiento existente de ib_umad, que mantiene los paquetes MAD recibidos en una lista ilimitada, plantea un riesgo de crecimiento incontrolado. A medida que las aplicaciones del espacio de usuario extraen paquetes de esta lista, es posible que la tasa de extracci\u00f3n no coincida con la tasa de paquetes entrantes, lo que puede provocar un posible desbordamiento de la lista. Para solucionar esto, introducimos un l\u00edmite al tama\u00f1o de la lista. Despu\u00e9s de considerar escenarios t\u00edpicos, como el procesamiento OpenSM, que puede manejar aproximadamente 100 000 paquetes por segundo, y el tiempo de espera de reintento de 1 segundo para la mayor\u00eda de los paquetes, establecemos el l\u00edmite de tama\u00f1o de la lista en 200 000. Los paquetes recibidos m\u00e1s all\u00e1 de este l\u00edmite se descartan, suponiendo que probablemente se agote el tiempo de espera cuando sean manejados por el espacio de usuario.
