I did see it be mentioned in a few. But it really isn't that big of a
problem, as all distros seemed to have their /dev/i2c* nodes set to:
$ ls -l /dev/i2c*
crw------- 1 root root 89, 0 Feb 23 13:02 /dev/i2c0
crw------- 1 root root 89, 0 Feb 23 13:02 /dev/i2c-0
crw------- 1 root root 89, 1 Feb 23 13:02 /dev/i2c1
crw------- 1 root root 89, 1 Feb 23 13:02 /dev/i2c-1

Which prevents any normal user from exploiting this issue.
