TLDRVuln - Cybersecurity Vulnerabilities Made Simple

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'
