      "value": "An integer overflow was found in the QEMU implementation of VMWare's paravirtual RDMA device in versions prior to 6.1.0. The issue occurs while handling a \"PVRDMA_REG_DSRHIGH\" write from the guest due to improper input validation. This flaw allows a privileged guest user to make QEMU allocate a large amount of memory, resulting in a denial of service. The highest threat from this vulnerability is to system availability."

      "value": "Se encontr\u00f3 un desbordamiento de enteros en la implementaci\u00f3n de QEMU del dispositivo RDMA paravirtual de VMWare en versiones anteriores a 6.1.0. El problema es producido mientras es manejado inapropiadamente una escritura \"PVRDMA_REG_DSRHIGH\" desde el hu\u00e9sped debido a una comprobaci\u00f3n de entrada inapropiada. Este fallo permite a un usuario invitado con privilegios hacer que QEMU asigne una gran cantidad de memoria, resultando en una denegaci\u00f3n de servicio. La mayor amenaza de esta vulnerabilidad es la disponibilidad del sistema"
