If any step of irdma_rereg_mr_trans fails after the new umem is allocated, it releases the umem, but does not set iwmr-&gt;region to NULL. The problem is that this failure is propagated to the user, who will then call ibv_dereg_mr (as they should). Then, the dereg_mr path will see a non-NULL umem and attempt to call ib_umem_release again.</p> <p>Fix this by setting iwmr-&gt;region to NULL after ib_umem_release.</p> <p>Fixed: 5ac388db27c4 (&#34;RDMA/irdma: Add support to re-register a memory region&#34;)</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>RDMA/irdma: Fix double free related to rereg_user_mr</p> <p>If IB_MR_REREG_TRANS is set during rereg_user_mr, the umem will be released and a new one will be allocated in irdma_rereg_mr_trans.
