DDoS Vulnerability Alert: Linux Kernel (ver 4.9+) (CVE-2018-5390)

A vulnerability known as “SegmentSmack” was recently discovered in Linux kernels of versions 4.9 or later. An attacker can exploit this vulnerability by remotely sending specially crafted TCP packets to prompt resource-intensive calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() via open ports, causing CPU saturation and ultimately achieving a denial-of-service (DoS) effect.
