      <title>CVE-2025-38401 — mtk-sd: Prevent memory corruption from DMA map failure</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2025-38401</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Linux&lt;/p&gt;
&lt;p&gt;In the Linux kernel, the following vulnerability has been resolved:&lt;/p&gt;
&lt;p&gt;mtk-sd: Prevent memory corruption from DMA map failure&lt;/p&gt;
&lt;p&gt;If msdc_prepare_data() fails to map the DMA region, the request is
not prepared for data receiving, but msdc_start_data() proceeds
the DMA with previous setting.
Since this will lead a memory corruption, we have to stop the
request operation soon after the msdc_prepare_data() fails to
prepare it.&lt;/p&gt;</description>
