I think that is well aligned what MISRA C++ is aiming at. At least several members of misra c++ are targeting that. See for example my p2070.

There is one inherent vulnerability that can not be solved by the C++ type system: dangling.

And there are several vulnerabilities, where the standard library lacks support and where misra suffers, because we can not provide libraries to use due to liability reasons and other reasons. For example, like the core guidelines support library providing span<T> before it made into the standard.

Peter
