In the Linux kernel, the following vulnerability has been resolved:
ipv6: fix WARNING in ip6routenetexitlate()
During the initialization of ip6routenetinitlate(), if file ipv6route or rt6stats fails to be created, the initialization is successful by default. Therefore, the ipv6route or rt6stats file doesn't be found during the remove in ip6routenetexitlate(). It will cause WRNING.
The following is the stack information: name 'rt6stats' WARNING: CPU: 0 PID: 9 at fs/proc/generic.c:712 removeprocentry+0x389/0x460 Modules linked in: Workqueue: netns cleanupnet RIP: 0010:removeprocentry+0x389/0x460 PKRU: 55555554 Call Trace: <TASK> opsexitlist+0xb0/0x170 cleanupnet+0x4ea/0xb00 processonework+0x9bf/0x1710 workerthread+0x665/0x1080 kthread+0x2e4/0x3a0 retfromfork+0x1f/0x30 </TASK>
