Submission + - Easy-To-Exploit Rooting Flaw Puts Linux Computers At Risk (csoonline.com)

itwbennett writes: The maintainers of Linux distributions are rushing to patch a privilege escalation vulnerability, tracked as CVE-2016-5195, that has has existed in the Linux kernel for the past nine years and is already being exploited in the wild. The Red Hat security team describes the flaw as a 'race' condition, 'in the way the Linux kernel's memory subsystem handles the copy-on-write (COW) breakage of private read-only memory mappings.' This allows an attacker who gains access to a limited user account to obtain root privileges and therefore take complete control over the system. The vulnerability was fixed last week by the Linux kernel developers and patches for Linux distributions, including Red Hat, Debian, Ubuntu, Gentoo and Suse, have been released or are in the process of being released.
