      <title>CVE-2026-72345 — net/mlx5: LAG, Fix off-by-one in single-FDB error rollback</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-72345</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/mlx5: LAG, Fix off-by-one in single-FDB error rollback&lt;/p&gt;
&lt;p&gt;On failure at index i, the reverse cleanup loop in
mlx5_lag_create_single_fdb() starts from i, so the failed index
itself is rolled back. That can operate on uninitialized state or
double-tear-down a rule the add_one path already self-rolled-back.&lt;/p&gt;
&lt;p&gt;Start the rollback from i - 1 so only successfully-installed entries
are undone.&lt;/p&gt;</description>
