Re: Where to report: root fails to edit other users file in sticky bit directory

Please note that it by default appears on Bullseye only. See that last mails regarding this issue, the related changed sysfs setting has identified already do:
sysctl fs.protected_regular=2
and retry the steps, which will then fail.
sysctl fs.protected_regular=0
to revert to default until up to Buster. From Bullseye on that defaults to "2" which prevents any user from write + "O_CREAT" to a file within a world-writeable + sticky bit directory (1777) that is owned by another user.

Best regards,
