App Control: Error: Unsupported Kernel Version (Linux)

Products

• Carbon Black App Control (formerly Cb Protection)

Issue/Introduction

Receiving healthcheck error: "Unsupported Kernel Version"

Environment

• Carbon Black App Control (Formerly CB Protection): All Supported Versions
• Linux: All Supported Versions

Cause

• Running an unsupported Linux OS
• Unsupported kernel modules are found in /lib/modules
• Additionally, kernels can reside in /lib/modules, but not actually running. The error will trigger on this as well.

Resolution

1. Confirm if the OS is currently supported:

2. A future release will differentiate if it's the OS itself or a module causing the error
