I know, I am rather late, but while preparing a new version of cups for
unstable, I found an upstream regression for the latest fix of
CVE-2024-35235. Four other commits are needed as well when cups only uses
a domain socket for communication.
In unstable I got #1073852 and #1074074, so this seems to be a valid use
case.

+ scheduler: Fix cupsd activated on-demand via socket
+
+ If only the expected cups.sock is set as listener in cupsd.conf, the
+ array Listeners was NULL. To prevent copying the code, do the array
+ allocation earlier and have only one check for Listeners, in
+ service_checkin() which is run every time cupsd starts.
+
+ Fixes #985
