Background
The cipso package is a component of the Linux Kernel, which is responsible for managing the Common IP Security Option (CIPSO) protocol. CIPSO provides a mechanism for labeling IP packets with security attributes. The sysctl interface in the cipso package allows users to configure various parameters related to CIPSO. However, a vulnerability has been discovered in the cipso package that involves data-races around the sysctl functionality.
Vulnerability Detail
The vulnerability in the cipso package revolves around data-races in the sysctl interface. Data-races occur when multiple threads or processes access shared data concurrently without proper synchronization. In this case, the sysctl interface is susceptible to data-races, which can lead to unexpected behavior, including race conditions, memory corruption, and crashes. The impact and attack plausibility of this vulnerability have not been proven yet.
