The problem is that since both variables are unsigned the &#34;dev-&gt;config_size - offset&#34; subtraction would result in a very high unsigned value.</p> <p>I think these checks might not be necessary because &#34;len&#34; and &#34;offset&#34; are supposed to already have been validated using the vhost_vdpa_config_validate() function. But I do not know the code perfectly, and I like to be safe.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>vduse: check that offset is within bounds in get_config()</p> <p>This condition checks &#34;len&#34; but it does not check &#34;offset&#34; and that could result in an out of bounds read if &#34;offset &gt; dev-&gt;config_size&#34;.
