      "value": "A use-after-free vulnerability was found in network namespaces code affecting the Linux kernel before 4.14.11. The function get_net_ns_by_id() in net/core/net_namespace.c does not check for the net::count value after it has found a peer network in netns_ids idr, which could lead to double free and memory corruption. This vulnerability could allow an unprivileged local user to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is thought to be unlikely."

      "value": "Se ha descubierto una vulnerabilidad en los nombres de espacio de red que afecta al kernel de Linux en versiones anteriores a la 4.14.11. La funci\u00f3n get_net_ns_by_id() en net/core/net_namespace.c no verifica el valor net::count una vez que ha encontrado una red peer en el ids netns_ids, lo que podr\u00eda conducir a una doble liberaci\u00f3n (double free) y a una corrupci\u00f3n de memoria. Esta vulnerabilidad podr\u00eda permitir que un usuario local sin privilegios provoque una corrupci\u00f3n de memoria en el sistema, desembocando en un cierre inesperado. Debido a la naturaleza del error, no puede descartarse totalmente el escalado de privilegios, aunque se cree que es improbable."
