Background
The Kernel package is a fundamental component of the Linux operating system, responsible for managing the system's core functionality. It includes various drivers for hardware devices, including the ethernet driver 'cpsw'. The cpsw driver enables communication between the system and ethernet devices. However, a vulnerability has been identified in this driver that can lead to a panic condition when interrupt coalescing is set via ethtool.
Vulnerability Detail
The vulnerability in the cpsw driver occurs when interrupt coalescing is configured using ethtool. This can trigger a panic condition, causing the system to crash. An attacker with the ability to manipulate the interrupt coalescing settings could potentially exploit this vulnerability to disrupt the system's operation or launch further attacks. The vulnerability was introduced in Linux Kernel version 5.15 and has been fixed in version 5.17.2.
How To Fix
No fixed version is published for this vulnerability.
