Using the WASM GC part instead of lieanr memory will solve that, right? I know it's not a possibility for all programs, but overall, it'll help?

Not at all, because a large majority of applications being ported to WASM are written in C and C++, with all security caveats it entails.

Garbage Collected implementations of C and C++ do exist, and only thing that their GC fixes is use after free.
