I don't think they are referring to the same vulnerabilities. The US government was publicly accusing the Chinese government of inserting backdoors in Huawei products, while at the same time seeking and exploiting vulnerabilities in Huawei products themselves. Perhaps this was an attempt to cover tracks by pre-emptively blaming the Chinese government for backdoors installed by the US government, should these backdoors ever be discovered. Personally I'm inclined to call Hanlon's razor on the hypocrisy of it all.
