Can it be fixed automatically?
Not fixed automatically. This failure needs the authoring tool or manual remediation; the automatic fix does not change it.
How to fix it by hand
Alternative text is human work: describe each image, formula or link in the authoring application (alt text field) or set it in the PDF editor's tag properties. No automatic tool can write a meaningful description for you.
