In the Linux kernel, the following vulnerability has been resolved:
ipv4: free net->ipv4.sysctl_local_reserved_ports after unregister_net_sysctl_table()
ipv4_sysctl_exit_net() is currently freeing net->ipv4.sysctl_local_reserved_ports too soon.
Only after unregister_net_sysctl_table() we can be sure no threads can possibly use the sysctls, including /proc/sys/net/ipv4/ip_local_reserved_ports.
