In the Linux kernel, the following vulnerability has been resolved:

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.
