I do not think anyone realized it was a "security" fix.  It was never
mentioned to the security@...nel.org alias, and I only picked it up
for the stable releases because someone said, "hey, here's another
trinity bugfix that userspace can trigger".  We fix those all the time,
every single stable kernel release.

The only thing different this time is someone took the time to develop a
simple exploit for others to use.

So I don't think this was any more or less "silent" than the normal
kernel bug fixes that happen every single week.
