Description
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.
The following is the stack information:
