I’m not affiliated with Talos. I’m an independent security researcher, so I don’t really know the details of the other bug. For my bug, I found it quite a while ago, and it looks like the credit process got missed after I reported it (it’s being sorted out now lol). As for exploitation: at least when I analyzed it back then, I didn’t see a viable way to get a shell. Even though it’s a stack overflow, I couldn’t find a memory layout that I could realistically overwrite in a useful way.
