      <title>CVE-2026-45973 — RDMA/mlx5: Fix UMR hang in LAG error state unload</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-45973</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;RDMA/mlx5: Fix UMR hang in LAG error state unload&lt;/p&gt;
&lt;p&gt;During firmware reset in LAG mode, a race condition causes the driver
to hang indefinitely while waiting for UMR completion during device
unload. See [1].&lt;/p&gt;
&lt;p&gt;In LAG mode the bond device is only registered on the master, so it
never sees sys_error events from the slave.
During firmware reset this causes UMR waits to hang forever on unload
as the slave is dead but the master hasn&amp;#39;t entered error state yet, so
UMR posts succeed but completions never arrive.&lt;/p&gt;
&lt;p&gt;Fix this by adding a sys_error notifier that gets registered before
MLX5_IB_STAGE_IB_REG and stays alive until after ib_unregister_device().
This ensures error events reach the bond device throughout teardown.&lt;/p&gt;
&lt;p&gt;[1]
