      <title>CVE-2026-72319 — ipvs: ensure inner headers in ICMP errors are in headroom</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-72319</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;ipvs: ensure inner headers in ICMP errors are in headroom&lt;/p&gt;
&lt;p&gt;Sashiko points out that after stripping the outer headers
with pskb_pull() we should ensure the inner IP headers
in ICMP errors from tunnels are present in the skb headroom
for functions like ipv4_update_pmtu(), icmp_send() and
IP_VS_DBG().&lt;/p&gt;
&lt;p&gt;Also, add more checks for the length of the inner headers.&lt;/p&gt;</description>
