Stack Clash isn't a vulnerability in the kernel - it's a vulnerability that allows an attacker to gain control over a process that they wouldn't normally be able to (e.g. a guid/suid'd program like 'sudo'). The kernel change simply makes it less likely for this kind of vulnerability to be exploited (though stack probing is needed to truly fix the issue).
