Note that the PoC relies on suid binaries, but it is not required for this. It can poison any file, like /etc/passwd in https://github.com/rootsecdev/cve_2026_31431/blob/main/ex...

Your suggestion is probably wise to follow nonetheless, though.

Ah yes, /etc/passwd indeed remains a great target for this :-)
