There is a DoS vulnerability in the Linux Kernel versions 4.9+ known as a SegmentSmack attack. Remote attackers may send TCP packets to Linux kernel to make it calls the very expensive functions tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() of the affected device which can lead to a denial of service. Maintaining the denial of service condition requires continuous two-way TCP sessions to a reachable open port. Thus, the attacks cannot be performed using spoofed IP addresses. (Vulnerability ID: HWPSIRT-2018-08114)
This vulnerability has been assigned a Common Vulnerabilities and Exposures (CVE) ID: CVE-2018-5390.

A remote attacker may be able to trigger a denial-of-service condition.
The vulnerability classification has been performed by using the CVSSv3 scoring system (http://www.first.org/cvss/specification-document).
Base Score: 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
Temporal Score: 6.5 (E:U/RL:O/RC:C)
Overall Score: 6.5
This vulnerability can be exploited only when the following conditions are present:
The attacker could continuous send two-way TCP sessions to the affected device.
Vulnerability details:
Remote attackers may send TCP packets to Linux kernel to make it calls the very expensive functions tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() of the affected device which can lead to a denial of service. Maintaining the denial of service condition requires continuous two-way TCP sessions to a reachable open port. Thus, the attacks cannot be performed using spoofed IP addresses.
