CVE-2018-6922 (opens in a new tab)How to fix?
There is no fixed version for Debian:10 kfreebsd-10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kfreebsd-10 package and not the kfreebsd-10 package as distributed by Debian.
See How to fix? for Debian:10 relevant fixed versions and status.
One of the data structures that holds TCP segments in all versions of FreeBSD prior to 11.2-RELEASE-p1, 11.1-RELEASE-p12, and 10.4-RELEASE-p10 uses an inefficient algorithm to reassemble the data. This causes the CPU time spent on segment processing to grow linearly with the number of segments in the reassembly queue. An attacker who has the ability to send TCP traffic to a victim system can degrade the victim system's network performance and/or consume excessive CPU by exploiting the inefficiency of TCP reassembly handling, with relatively small bandwidth cost.
