      "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad:\n\nfs: ntfs3: soluci\u00f3n de bucle infinito en attr_load_runs_range con metadatos inconsistentes\n\nSe encontr\u00f3 un error de bucle infinito en el sistema de archivos ntfs3 que puede conducir a una condici\u00f3n de Denegaci\u00f3n de Servicio (DoS).\n\nUna imagen NTFS malformada puede causar un bucle infinito cuando un encabezado de atributo indica una lista de ejecuciones vac\u00eda, mientras que las entradas de directorio lo referencian como si contuviera datos reales. En NTFS, establecer evcn=-1 con svcn=0 es una forma v\u00e1lida de representar una lista de ejecuciones vac\u00eda, y run_unpack() lo maneja correctamente verificando si evcn + 1 es igual a svcn y retornando anticipadamente sin analizar ning\u00fan dato de ejecuci\u00f3n. Sin embargo, esto crea un problema cuando hay inconsistencia de metadatos, donde el encabezado del atributo afirma estar vac\u00edo (evcn=-1) pero el llamador espera leer datos reales. Cuando run_unpack() retorna \u00e9xito inmediatamente al ver esta condici\u00f3n, deja el runs_tree sin inicializar con run-\u0026gt;runs como NULL. La funci\u00f3n llamadora attr_load_runs_range() asume que un retorno exitoso significa que las ejecuciones fueron cargadas y establece clen en 0, esperando que la siguiente llamada a run_lookup_entry() tenga \u00e9xito. Debido a que runs_tree permanece sin inicializar, run_lookup_entry() sigue fallando, y el bucle incrementa vcn en cero (vcn += 0), lo que lleva a un bucle infinito.\n\nEste parche agrega un contador de reintentos para detectar cu\u00e1ndo run_lookup_entry() falla consecutivamente despu\u00e9s de attr_load_runs_vcn(). Si la ejecuci\u00f3n a\u00fan no se encuentra en el segundo intento, indica metadatos corruptos y retorna -EINVAL, previniendo la vulnerabilidad de Denegaci\u00f3n de Servicio (DoS)."
