CVE-2016-5195: Linux Kernel Race Condition Vulnerability

First published: Thu Oct 13 2016(Updated: )

A race condition was found in the way Linux kernel's memory subsystem handled breakage of the read only private mappings COW situation on write access. An unprivileged local user could use this flaw to gain write access to otherwise read only memory mappings and thus increase their privileges on the system. Red Hat is aware of this issue and if you have questions about the affectedness of your system please contact Red Hat Support.
