kernel: ipv4: free net->ipv4.sysctl_local_reserved_ports after unregister_net_sysctl_table()

A flaw was found in the Linux kernel's IPv4 networking component. The ipv4sysctlexitnet function prematurely frees the net-ipv4.sysctllocalreservedports memory. This can lead to a use-after-free vulnerability, where other threads might attempt to access deallocated memory. Such an issue can resul...
