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

  - neighbour: Fix null-ptr-deref in neigh_flush_dev(). kernel test robot reported null-ptr-deref in     neigh_flush_dev(). [0] The cited commit introduced per-netdev neighbour list and converted     neigh_flush_dev() to use it instead of the global hash table. One thing we missed is that     neigh_table_clear() calls neigh_ifdown() with NULL dev. Let's restore the hash table iteration. Note that     IPv6 module is no longer unloadable, so neigh_table_clear() is called only when IPv6 fails to initialise,     which is unlikely to happen.
