      <title>CVE-2026-80643 — EDAC/igen6: Fix call trace due to missing release()</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-80643</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;EDAC/igen6: Fix call trace due to missing release()&lt;/p&gt;
&lt;p&gt;When unloading the igen6_edac driver, there is a call trace:&lt;/p&gt;
&lt;p&gt;Device &amp;#39;(null)&amp;#39; does not have a release() function, it is broken and must be fixed.
  See Documentation/core-api/kobject.rst.
  WARNING: drivers/base/core.c:2567 at device_release+0x84/0x90, CPU#5: rmmod/127209
  ...
  RIP: 0010:device_release+0x84/0x90
  Call Trace:
   &amp;lt;TASK&amp;gt;
   kobject_put+0x8c/0x220
   put_device+0x17/0x30
   igen6_unregister_mcis+0xa2/0xe0 [igen6_edac]
   igen6_remove+0x82/0xb0 [igen6_edac]
   ...&lt;/p&gt;
&lt;p&gt;Fix the call trace by providing empty release() functions for the
memory controller devices.&lt;/p&gt;</description>
