      <title>CVE-2024-46739 — uio_hv_generic: Fix kernel NULL pointer dereference in hv_uio_rescind</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2024-46739</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;uio_hv_generic: Fix kernel NULL pointer dereference in hv_uio_rescind&lt;/p&gt;
&lt;p&gt;For primary VM Bus channels, primary_channel pointer is always NULL. This
pointer is valid only for the secondary channels. Also, rescind callback
is meant for primary channels only.&lt;/p&gt;
&lt;p&gt;Fix NULL pointer dereference by retrieving the device_obj from the parent
for the primary channel.&lt;/p&gt;</description>
