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

  - In the Linux kernel, the following vulnerability has been resolved: IB/hfi1: Fix sdma.h tx->num_descs off-     by-one error Unfortunately the commit `fd8958efe877` introduced another error causing the `descs` array to     overflow. This reults in further crashes easily reproducible by `sendmsg` system call.

This results in a panic when     the send completion runs. The exact panic varies depending on what elements of the container structure get     corrupted. The fix is to use the correct expression in _pad_sdma_tx_descs() to test the need to expand the     descriptor array. With this patch the crashes are no longer reproducible and the machine is stable.
