Background
The igmp package is a component of the Linux Kernel, which is responsible for handling Internet Group Management Protocol (IGMP) messages. IGMP is a network-layer protocol used by hosts and adjacent routers on an Internet Protocol (IP) network to establish multicast group memberships. The sysctl_igmp_llm_reports function in the igmp package is susceptible to data races, which can lead to unpredictable behavior and potential security vulnerabilities.
Vulnerability Detail
The data races in the sysctl_igmp_llm_reports function can result in concurrent access to shared data without proper synchronization. This can lead to inconsistent or corrupted data, unexpected behavior, and potential security vulnerabilities. Attackers may be able to exploit these data races to manipulate the behavior of the IGMP protocol, potentially leading to denial-of-service attacks or unauthorized access to sensitive information.
How To Fix
No fixed version is published for this vulnerability.
