      <title>CVE-2026-72351 — gue: validate REMCSUM private option length</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-72351</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;gue: validate REMCSUM private option length&lt;/p&gt;
&lt;p&gt;GUE private flags can indicate that remote checksum offload metadata is
present. The private flags field itself is accounted for by
guehdr_flags_len(), but guehdr_priv_flags_len() currently returns 0 even
when GUE_PFLAG_REMCSUM is set.&lt;/p&gt;
&lt;p&gt;This lets a packet with only the private flags field pass
validate_gue_flags(), after which gue_remcsum() and gue_gro_remcsum()
read the missing REMCSUM start/offset fields from the following bytes.&lt;/p&gt;
&lt;p&gt;Account for GUE_PLEN_REMCSUM when GUE_PFLAG_REMCSUM is present so that
malformed packets are rejected during option validation.&lt;/p&gt;</description>
