As reported in https://github.com/llvm/llvm-project/issues/89710, the %s code used for `comm` could and probably does, overflow the buffer. Likely we haven't seen it cause problems because the following data is overwritten right afterwards. Also scanf isn't a great choice here as this `comm` can include many characters that might trip up %s. We don't actually use `comm`, so parse but don't store it so we're not overflowing anything.
