Background
The Kernel is a critical component of the Linux operating system that provides core functionalities and interfaces with hardware devices. It manages system resources, facilitates communication between software and hardware, and ensures the stability and security of the system. The MultiPath TCP (mptcp) is an extension to the TCP protocol that allows for the simultaneous use of multiple network paths, improving performance and reliability. However, a vulnerability has been discovered in the mptcp implementation in the Kernel, which can lead to data stream corruption.
Vulnerability Detail
The vulnerability in the mptcp implementation in the Kernel can result in data stream corruption. This can occur when processing network traffic using the mptcp protocol, potentially leading to data integrity issues and unexpected behavior. The vulnerability was introduced in version v5.7 of the Linux Kernel and was fixed in version v5.10.42. The impact and attack plausibility of this vulnerability have not been proven yet.
