      "value": "A parameter verification issue was discovered in Xen through 4.9.x. The function `alloc_heap_pages` allows callers to specify the first NUMA node that should be used for allocations through the `memflags` parameter; the node is extracted using the `MEMF_get_node` macro. While the function checks to see if the special constant `NUMA_NO_NODE` is specified, it otherwise does not handle the case where `node >= MAX_NUMNODES`. This allows an out-of-bounds access to an internal array."

      "value": "Existe un problema de verificaci\u00f3n de par\u00e1metros en Xen hasta la versi\u00f3n 4.9.x. La funci\u00f3n `alloc_heap_pages` permite que los que la llaman especifiquen el primer nodo NUMA que deber\u00eda usarse para asignaciones a trav\u00e9s del par\u00e1metro `memflags`; el nodo se extrae empleando la macro `MEMF_get_node`. Aunque la funci\u00f3n comprueba si se especifica la constante especial `NUMA_NO_NODE`, no gestiona el caso en el que `node >= MAX_NUMNODES`. Esto permite el acceso fuera de l\u00edmites a un array interno."
