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

  - xfrm: delete x->tunnel as we delete x The ipcomp fallback tunnels currently get deleted (from the various     lists and hashtables) as the last user state that needed that fallback is destroyed (not deleted). If a     reference to that user state still exists, the fallback state will remain on the hashtables/lists,     triggering the WARN in xfrm_state_fini. Because of those remaining references, the fix in commit     f75a2804da39 (xfrm: destroy xfrm_state synchronously on net exit path) is not complete. We recently     fixed one such situation in TCP due to defered freeing of skbs (commit 9b6412e6979f (tcp: drop secpath at     the same time as we currently drop dst)). This can also happen due to IP reassembly: skbs with a secpath     remain on the reassembly queue until netns destruction. If we can't guarantee that the queues are flushed     by the time xfrm_state_fini runs, there may still be references to a (user) xfrm_state, preventing the     timely deletion of the corresponding fallback state. Instead of chasing each instance of skbs holding a     secpath one by one, this patch fixes the issue directly within xfrm, by deleting the fallback state as     soon as the last user state depending on it has been deleted. Destruction will still happen when the final     reference is dropped. A separate lockdep class for the fallback state is required since we're going to     lock x->tunnel while x is locked.
