Local-Privilege Escalation Flaw in Linux Kernel Allows Root Access

September 28, 2018 by Raaghav Sharma 1 Comment

A local-privilege escalation vulnerability in the Linux kernel affects all current versions of Red Hat Enterprise Linux and CentOS, even in their default/minimal installations. It would allow an attacker to obtain full administrator privileges over the targeted system, and from there potentially pivot to other areas of the network.

    To successfully exploit this vulnerability, attackers need to have access to the targeted system and run their exploit that leads to a buffer overflow, thereby resulting in the execution of malicious code and achieving complete control of the affected system. In addition, this issue does not affect 32-bit systems as they do not have a large enough address space to exploit this flaw. Systems with less than 32GB of memory are unlikely to be affected by this issue due to memory demands during exploitation,” an advisory released by Red Hat reads.
