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

  - netfilter: nf_tables: always release netdev hooks from notifier This reverts netfilter: nf_tables: skip     netdev events generated on netns removal. The problem is that when a veth device is released, the veth     release callback will also queue the peer netns device for removal. Its possible that the peer netns is     also slated for removal. In this case, the device memory is already released before the pre_exit hook of     the peer netns runs: BUG: KASAN: slab-use-after-free in nf_hook_entry_head+0x1b8/0x1d0 Read of size 8 at     addr ffff88812c0124f0 by task kworker/u8:1/45 Workqueue: netns cleanup_net Call Trace:
    nf_hook_entry_head+0x1b8/0x1d0 __nf_unregister_net_hook+0x76/0x510 nft_netdev_unregister_hooks+0xa0/0x220
    __nft_release_hook+0x184/0x490 nf_tables_pre_exit_net+0x12f/0x1b0 .. Order is: 1. First netns is released,     veth_dellink() queues peer netns device for removal 2. peer netns is queued for removal 3. peer netns     device is released, unreg event is triggered 4. unreg event is ignored because netns is going down 5.
    pre_exit hook calls nft_netdev_unregister_hooks but device memory might be free'd already.
