In the Linux kernel, the following vulnerability has been resolved: ipvs: fix WARNING in __ip_vs_cleanup_batch() During the initialization of ip_vs_conn_net_init(), if file ip_vs_conn or ip_vs_conn_sync fails to be created, the initialization is successful by default. Therefore, the ip_vs_conn or ip_vs_conn_sync file doesn't be found during the remove.
