Background

The Kernel package is a critical component of the Linux operating system, responsible for managing the system's core functionality. It provides essential services such as process management, memory management, and device drivers. The vulnerability in question affects the TCP (Transmission Control Protocol) implementation within the Kernel package.

Vulnerability Detail

The vulnerability arises from the improper allocation of the table_perturb variable in the TCP implementation. Instead of using the recommended alloc_large_system_hash() function, an incorrect allocation method is employed. This vulnerability can potentially be exploited by attackers to manipulate the table_perturb value, leading to various security issues. While the exact impact and attack vectors have not been proven, it is crucial to address this vulnerability to ensure the integrity and security of the system.
