      <title>CVE-2026-53232 — net: phy: clean the sfp upstream if phy probing fails</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-53232</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;net: phy: clean the sfp upstream if phy probing fails&lt;/p&gt;
&lt;p&gt;Sashiko reported that we don&amp;#39;t call sfp_bus_del_upstream() in the probe
failure path, so let&amp;#39;s add it, otherwise the sfp-bus is left with a
dangling &amp;#39;upstream&amp;#39; field, that may be used later on during SFP events.&lt;/p&gt;
&lt;p&gt;This issue existed before the generic phylib sfp support, back when
drivers were calling phy_sfp_probe themselves.&lt;/p&gt;</description>
