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

  - RDMA/mlx5: Fix error flow upon firmware failure for RQ destruction Upon RQ destruction if the firmware     command fails which is the last resource to be destroyed some SW resources were already cleaned regardless     of the failure. Now properly rollback the object to its original state upon such failure. In order to     avoid a use-after free in case someone tries to destroy the object again, which results in the following     kernel trace: refcount_t: underflow; use-after-free.
