You can debug the ProductPageController there you can see how metaDescription being set. In Hybris OOTB(I'm referring 6.7), meta description being set using product description. So you need to check the same in your codebase. If you haven't customized that part so far then tries setting product description and check.
ProductPageController
final String metaKeywords = MetaSanitizerUtil.sanitizeKeywords(productData.getKeywords());
final String metaDescription = MetaSanitizerUtil.sanitizeDescription(productData.getDescription());
setUpMetaData(model, metaKeywords, metaDescription);
AbstractPageController
protected void setUpMetaData(final Model model, final String metaKeywords, final String metaDescription)
{
final List<MetaElementData> metadata = new LinkedList<>();
metadata.add(createMetaElement("keywords", metaKeywords));
metadata.add(createMetaElement("description", metaDescription));
model.addAttribute("metatags", metadata);
}
