      <title>CVE-2022-49389 — usb: usbip: fix a refcount leak in stub_probe()</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2022-49389</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;usb: usbip: fix a refcount leak in stub_probe()&lt;/p&gt;
&lt;p&gt;usb_get_dev() is called in stub_device_alloc(). When stub_probe() fails
after that, usb_put_dev() needs to be called to release the reference.&lt;/p&gt;
&lt;p&gt;Fix this by moving usb_put_dev() to sdev_free error path handling.&lt;/p&gt;
&lt;p&gt;Find this by code review.&lt;/p&gt;</description>
