CloudLinux 7 is also based on RHEL, specifically on Red Hat Enterprise Linux 7 series, so it always receives the latest security patches as soon as they are released upstream. CVE-2017-6074 is a use-after-free flaw discovered in Linux kernel’s DCCP (Datagram Congestion Control Protocol). It could be exploited by an unprivileged local attacker to escalate his/her privileges on the vulnerable system by altering the kernel memory. Red Hat marked the security issue as important and you should update your installations immediately to kernel version 3.10.0-427.36.1.lve1.4.39 if you’re running CloudLinux 7.
