Technical 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:

name 'ip_vs_conn_sync'
