      <title>CVE-2026-43101 — ipv6: ioam: fix potential NULL dereferences in __ioam6_fill_trace_data()</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-43101</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;ipv6: ioam: fix potential NULL dereferences in __ioam6_fill_trace_data()&lt;/p&gt;
&lt;p&gt;We need to check __in6_dev_get() for possible NULL value, as
suggested by Yiming Qian.&lt;/p&gt;
&lt;p&gt;Also add skb_dst_dev_rcu() instead of skb_dst_dev(),
and two missing READ_ONCE().&lt;/p&gt;
&lt;p&gt;Note that @dev can&amp;#39;t be NULL.&lt;/p&gt;</description>
