      <title>CVE-2025-40170 — net: use dst_dev_rcu() in sk_setup_caps()</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2025-40170</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: use dst_dev_rcu() in sk_setup_caps()&lt;/p&gt;
&lt;p&gt;Use RCU to protect accesses to dst-&amp;gt;dev from sk_setup_caps()
and sk_dst_gso_max_size().&lt;/p&gt;
&lt;p&gt;Also use dst_dev_rcu() in ip6_dst_mtu_maybe_forward(),
and ip_dst_mtu_maybe_forward().&lt;/p&gt;
&lt;p&gt;ip4_dst_hoplimit() can use dst_dev_net_rcu().&lt;/p&gt;</description>
