Summary
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: name 'rt6_stats' WARNING: CPU: 0 PID: 9 at fs/proc/generic.c:712 remove_proc_entry+0x389/0x460 Modules linked in: Workqueue: netns cleanup_net RIP: 0010:remove_proc_entry+0x389/0x460 PKRU: 55555554 Call Trace: <TASK> ops_exit_list+0xb0/0x170 cleanup_net+0x4ea/0xb00 process_one_work+0x9bf/0x1710 worker_thread+0x665/0x1080 kthread+0x2e4/0x3a0 ret_from_fork+0x1f/0x30 </TASK>
