The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - RDMA: During rereg_mr ensure that REREG_ACCESS is compatible If IB_MR_REREG_ACCESS changes from RO to RW     then the umem has to be re-evaluated to ensure it is properly pinned as RW. Since the umem is hidden     inside each driver's mr struct add a ib_umem_check_rereg() function that each driver has to call before     processing IB_MR_REREG_ACCESS. mlx4 has to retain its duplicate ib_access_writable check because it     implements IB_MR_REREG_ACCESS | IB_MR_REREG_TRANS by changing both items in place sequentially while the     MR is live, so it will continue to not support this combination. (CVE-2026-52908)

Note that Nessus relies on the presence of the package as reported by the vendor.
