Security Advisory - SegmentSmack Vulnerability in Linux Kernel

  • SA No:huawei-sa-20181031-02-linux
  • Initial Release Date: Oct 31, 2018
  • Last Release Date: Aug 05, 2020

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. 
Huawei has released software updates to fix this vulnerability. This advisory is available at the following link:
