Background
The Kernel package is an essential component of the Linux operating system. It provides the core functionality and interfaces for the system's hardware and software components. The Transmission Control Protocol (TCP) Internet Protocol (IP) Core (TIPC) is a communication protocol implemented within the Kernel package. TIPC enables communication between processes running on different nodes in a cluster. It utilizes domain records to manage communication domains. However, a vulnerability has been identified in the size validations for received domain records in TIPC.
Vulnerability Detail
The vulnerability in TIPC's size validations for received domain records can potentially lead to security issues. The vulnerability was introduced in version v4.8 of the Linux Kernel and was fixed in version v5.16.9. An attacker could exploit this vulnerability to manipulate the size of received domain records, potentially causing buffer overflows or other memory-related issues. The impact and attack plausibility of this vulnerability have not been proven yet.
