Background

The cipso package is a component of the Linux Kernel ecosystem. It provides functionality related to the Common IP Security Option (CIPSO) protocol. CIPSO is used for labeling network packets with security attributes. The sysctl interface in the cipso package allows users to configure various kernel 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 arises due to data-races around 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 unpredictable behavior and potential security risks. The impact and attack plausibility of this vulnerability have not been proven yet. The vulnerability was introduced in version v2.6.19 of the Linux Kernel and has been fixed in version v5.15.56 by commit 07b0caf8aeb9b82e6ecc6c292a3e47c7fcdb1148.
