      <title>CVE-2026-46172 — ipv6: xfrm6: release dst on error in xfrm6_rcv_encap()</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-46172</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Linux, Siemens SIMATIC S7-1500 CPU 1518-4 PN/DP MFP, Siemens SIMATIC S7-1500 CPU 1518F-4 PN/DP MFP, Siemens SIPLUS S7-1500 CPU 1518-4 PN/DP MFP&lt;/p&gt;
&lt;p&gt;In the Linux kernel, the following vulnerability has been resolved:&lt;/p&gt;
&lt;p&gt;ipv6: xfrm6: release dst on error in xfrm6_rcv_encap()&lt;/p&gt;
&lt;p&gt;xfrm6_rcv_encap() performs an IPv6 route lookup when the skb does not
already have a dst attached. ip6_route_input_lookup() returns a
referenced dst entry even when the lookup resolves to an error route.&lt;/p&gt;
&lt;p&gt;If dst-&amp;gt;error is set, xfrm6_rcv_encap() drops the skb without attaching
the dst to the skb and without releasing the reference returned by the
lookup. Repeated packets hitting this path therefore leak dst entries.&lt;/p&gt;
&lt;p&gt;Release the dst before jumping to the drop path.&lt;/p&gt;</description>
