CVE-2020-11898 is a vulnerability in the Treck TCP/IP stack affecting versions before 6.0.1.66, specifically in the IPv4/ICMPv4 packet-handling logic. The issue is caused by improper handling of an IPv4/ICMPv4 length parameter inconsistency, where malformed packet length fields are not validated correctly. According to the provided content, this can lead to an out-of-bounds read during processing of a specially crafted network packet. The vulnerability is part of the Ripple20 set of Treck stack flaws and affects embedded products and devices that incorporate the vulnerable Treck implementation, including implementations distributed under alternate names such as Kasago TCP/IP, ELMIC, Net+ OS, Quadnet, GHNET v2, Kwiknet, and AMX.
