      <title>CVE-2026-98498 — net/mlx5: Fix rev_entry reference leak in mlx5_tc_ct_shared_counter_get()</title>
      <link>https://db.gcve.eu/vuln/cve-2026-98498</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: Fix rev_entry reference leak in mlx5_tc_ct_shared_counter_get()&lt;/p&gt;
&lt;p&gt;When the reverse entry is found but its counter is already being
released, refcount_inc_not_zero() fails and the reference taken by
mlx5_tc_ct_entry_get() is never dropped before falling through to
create_counter.  Drop it so the reverse entry is not kept alive forever
by a shared counter lookup that did not use it.&lt;/p&gt;</description>
