Security Advisory - SegmentSmack Vulnerability in Linux Kernel
- SA No:huawei-sa-20181031-01-linux
- Initial Release Date: 2018-10-31
- Last Release Date: 2019-12-11
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:
