      <title>CVE-2026-43312 — media: i2c: ov5647: Initialize subdev before controls</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-43312</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;media: i2c: ov5647: Initialize subdev before controls&lt;/p&gt;
&lt;p&gt;In ov5647_init_controls() we call v4l2_get_subdevdata, but it is
initialized by v4l2_i2c_subdev_init() in the probe, which currently
happens after init_controls(). This can result in a segfault if the
error condition is hit, and we try to access i2c_client, so fix the
order.&lt;/p&gt;</description>
