Background
The igmp package is a part of the Linux Kernel ecosystem. It is responsible for handling Internet Group Management Protocol (IGMP) messages, which are used for managing multicast group memberships on IP networks. The package provides functionality for joining and leaving multicast groups, as well as querying group membership information. The vulnerability in question involves data-races around the sysctl_igmp_llm_reports function, which can lead to potential security issues.
Vulnerability Detail
The vulnerability arises from data-races around the sysctl_igmp_llm_reports function in the igmp package. Data-races occur when multiple threads access shared data concurrently without proper synchronization, leading to unpredictable behavior and potential security vulnerabilities. In this case, the data-races can result in race conditions, memory corruption, or other unintended consequences. The impact and attack plausibility of this vulnerability have not been proven yet. The vulnerability was introduced in version v4.3 of the Linux Kernel and has been fixed in version v5.10.134.
