      <title>CVE-2025-68189 — drm/msm: Fix GEM free for imported dma-bufs</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2025-68189</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;drm/msm: Fix GEM free for imported dma-bufs&lt;/p&gt;
&lt;p&gt;Imported dma-bufs also have obj-&amp;gt;resv != &amp;amp;obj-&amp;gt;_resv.  So we should
check both this condition in addition to flags for handling the
_NO_SHARE case.&lt;/p&gt;
&lt;p&gt;Fixes this splat that was reported with IRIS video playback:&lt;/p&gt;
