Background

The Kernel package is a critical 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) over Internet Protocol (IP) Connections (TIPC) is a communication protocol implemented in the Kernel package. TIPC allows processes to communicate with each other across a network. TIPC uses domain records to manage communication domains. These domain records contain important information about the domains, such as their size and configuration.

Vulnerability Detail

The vulnerability identified in the TIPC implementation of the Kernel package relates to inadequate size validations for received domain records. This means that when a TIPC domain record is received, the Kernel does not properly validate its size, potentially leading to buffer overflows or other memory corruption issues. An attacker could exploit this vulnerability by sending specially crafted domain records to a vulnerable system, causing it to execute arbitrary code or crash. The impact of this vulnerability could range from privilege escalation to denial of service.

How To Fix

No fixed version is published for this vulnerability.

The vulnerability has been fixed in Linux Kernel version v4.19.229 by commit f1af11edd08dd8376f7a84487cbb0ea8203e3a1d. To fix the vulnerability, users should update their Kernel package to this version or a later one. It is recommended to regularly update the Kernel package to ensure the latest security patches are applied.
