Description Alexander Bergmann 2016-05-17 06:44:29 UTC

rh#1327484

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.
