Issue

Given these icons are images that are important for the understanding of the document (content images) these icons lack proper alternative text.

Remediation

For content images

    <svg focusable="false" width="24" height="28" viewBox="0 0 24 28"
            role="img" aria-labelledby="svg-title">
        <title id="svg-title"> Menu </title>
        <!-- svg content -->
    </svg>

For presentational images

<svg focusable="false" role="presentation" aria-hidden="true"> ... </svg>
