Background
The Kernel package is an integral part of the Linux operating system. It provides the core functionality and interfaces for the system. The Transmission Control Protocol (TCP) and Internet Protocol (IP) are essential components of the Kernel package. The Transparent Inter-Process Communication (TIPC) protocol is a communication mechanism within the Kernel that allows processes to exchange messages across nodes in a cluster. TIPC uses domain records to manage communication between nodes.
Vulnerability Detail
The vulnerability identified in TIPC relates to insufficient size validations for received domain records. This vulnerability was introduced in version v4.8 of the Linux Kernel and was fixed in version v5.4.179. An attacker could exploit this vulnerability by sending specially crafted domain records, leading to potential memory corruption or denial of service. The impact and attack plausibility of this vulnerability have not been proven yet.
