This has nothing to do with syslog. These are kernel printk messages.
They also go to syslog for logging in files but they go straight to the
kernel console as defined at bootup. Unless you have configured serial
consoles, the "console" for the kernel is the virtual terminals.

It's the kernel itself.
In a VC:
setterm --msg off
-msg [on|off] (virtual consoles only)
Enables or disables the sending of kernel printk()
messages to the console.
