A 731-byte Python script, downloaded and piped directly into the interpreter, is enough to give any unprivileged local user a root shell. No race conditions. No kernel offsets to guess. Just a straight-line exploit that works on every major Linux distribution going back to 2017. If you run Linux servers — especially multi-tenant ones — you need to patch this now.
