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...

CVE-2026-64002

CVE-2026-64002: Linux kernel fix for freeing net->ipv4.sysctl_local_reserved_ports too early. The issue occurs because ipv4_sysctl_exit_net() frees the pointer before unregister_net_sysctl_table(), risking use of sysctls such as /proc/sys/net/ipv4/ip_local_reserved_ports. The resolution ensure...
