CVE-2022-2526

Se ha encontrado una vulnerabilidad de uso de memoria previamente liberada en systemd. Este problema ocurre debido a que las funciones on_stream_io() y dns_stream_complete() en "resolved-dns-stream.c" no incrementan el conteo de referencias para el objeto DnsStream. Por lo tanto, otras funciones y callbacks llamados pueden hacer referencia al objeto DNSStream, causando un uso de memoria previamente liberada cuando la referencia sigue usándose más tarde
