      "value": "An integer underflow in dpdk versions before 18.11.10 and before 19.11.5 in the `move_desc` function can lead to large amounts of CPU cycles being eaten up in a long running loop. An attacker could cause `move_desc` to get stuck in a 4,294,967,295-count iteration loop. Depending on how `vhost_crypto` is being used this could prevent other VMs or network tasks from being serviced by the busy DPDK lcore for an extended period."

      "value": "Un subdesbordamiento de enteros en dpdk versiones anteriores a 18.11.10 y anteriores a 19.11.5 en la funci\u00f3n \"move_desc\" puede conllevar a que sean consumidos grandes cantidades de ciclos de CPU en un bucle de larga ejecuci\u00f3n. Un atacante podr\u00eda causar que \"move_desc\" se atasque en un bucle de iteraci\u00f3n de 4.294.967.295 conteos. Dependiendo de c\u00f3mo se use \"vhost_crypto\", esto podr\u00eda impedir que otras VM o tareas de la red sean atendidas por el lcore DPDK ocupado durante un per\u00edodo prolongado"
