In the Linux kernel, the following vulnerability has been resolved:
ipv6: fix WARNING in ip6_route_net_exit_late()
During the initialization of ip6_route_net_init_late(), if file
ipv6_route or rt6_stats fails to be created, the initialization is
successful by default. Therefore, the ipv6_route or rt6_stats file
doesn't be found during the remove in ip6_route_net_exit_late(). It
will cause WRNING.
The following is the stack information:
