I'm puzzled. It is not just documented that posix_spawn_file_actions_addopen() should make a copy, but the glibc implementation actually makes it: see for example https://github.com/bminor/glibc/blob/09533208febe923479261a27b7691abef297d604/posix/spawn_faction_addopen.c . I don't see a way of corrupting this memory. Can non-glibc implementation be used here?
