Background
The Kernel package is a fundamental component of the Linux operating system. It provides the core functionality and interfaces for the system's hardware, software, and processes. The sctp module within the Kernel package is responsible for implementing the Stream Control Transmission Protocol (SCTP), which is a transport layer protocol used for reliable and ordered message delivery. This vulnerability, identified as GSD-2021-1000331, affects the sctp module and can potentially lead to security issues.
Vulnerability Detail

This delay can result in incorrect state management and potential security vulnerabilities. While the impact and attack plausibility have not been proven, it is crucial to address this vulnerability to ensure the integrity and security of the system. The vulnerability was introduced in version v5.7 of the Linux Kernel and has been fixed in version v5.10.38.
