What's the problem with the old logic in the mem handling? (Why does this
need a CVE?)

This is a possible local privilege escalation issue on a system with
ASLR disabled, combined with other exploitation techniques.

Detailed information can be found here,

We have released an update for Red Hat Enterprise Linux 6,

Please update the kernel as soon as possible.

PS: On Red Hat Enterprise Linux 6, /bin/su (coreutils) and
/usr/bin/gpasswd (shadow-utils) are protected at compile time by PIE.

Thanks, Eugene
