CVE-2016-3707
First published: Fri Apr 15 2016(Updated: )
A flaw was found in the kernel-rt in which an attacker could submit a specially crafted ICMP echo request which can trigger a sysrq function based on values in the ICMP packet. This feature was introduced in the kernel-rt only and is not shipping with standard Red Hat Enterprise Linux kernels. Remote attacker could exploit this feature using bruteforce to submit arbitrary SysRq commands.
