The good news is that in order to exploit the new vulnerability, the attacker first has to obtain kernel level access to the system somehow - by exploiting some other vulnerabilities perhaps.
The bad news is once Sinkclose attack is performed, it can be hard to detect and mitigate: it can even survive an OS reinstall.
