      <title>CVE-2026-45910 — RDMA/rxe: Fix race condition in QP timer handlers</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-45910</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/rxe: Fix race condition in QP timer handlers&lt;/p&gt;
&lt;p&gt;I encontered the following warning:
 WARNING: drivers/infiniband/sw/rxe/rxe_task.c:249 at rxe_sched_task+0x1c8/0x238 [rdma_rxe], CPU#0: swapper/0/0

 WARNING: lib/refcount.c:28 at refcount_warn_saturate+0x138/0x1a0, CPU#3: kworker/u17:4/93400&lt;/p&gt;
&lt;p&gt;The issue is caused by a race condition between retransmit_timer() and
rxe_destroy_qp, leading to the Queue Pair&amp;#39;s (QP) reference count dropping
to zero during timer handler execution.&lt;/p&gt;
&lt;p&gt;It seems this warning is harmless because rxe_qp_do_cleanup() will flush
all pending timers and requests.&lt;/p&gt;
&lt;p&gt;Example of flow causing the issue:&lt;/p&gt;
