Background
The Linux Kernel is a widely used open-source operating system kernel that serves as the foundation for various Linux distributions. It provides essential functionality for managing hardware resources, process scheduling, and device drivers. The Marvell Prestera driver is responsible for handling network port events in the Linux Kernel. These events include link state changes, such as a network cable being plugged or unplugged. However, a vulnerability has been discovered in the Marvell Prestera driver that affects the handling of port events during initialization.
Vulnerability Detail
The vulnerability in the Marvell Prestera driver occurs during the initialization process. It can lead to incorrect handling of port events, potentially causing network connectivity issues or incorrect reporting of link state changes. An attacker could exploit this vulnerability to disrupt network communication or manipulate the reported link status, leading to potential security risks or operational problems. The vulnerability was introduced in version v5.10 of the Linux Kernel and has been fixed in version v5.10.37.
