KernelCare cronjob results in: Unknown Kernel

Symptoms

The KernelCare cronjob fails with the following where $KERNEL_RELEASE is the running kernel version.

Unknown Kernel (CentOS Linux $KERNEL_RELEASE)

Running the command listed below in SSH or "WHM / Terminal" as root also results in the same message:

# kcarectl --check
Unknown kernel (CentOS Linux $KERNEL_RELEASE), no patches available

Description 

KernelCare will return "Unknown Kernel" when the server's kernel is not compatible with KernelCare. This typically occurs when updating to the latest kernel before KernelCare has released a patch.

Workaround

Confirm KernelCare has released a patch for the kernel.

Is my kernel patched by KernelCare?
