Dirty Cow – CVE-2016-5195

One vulnerability in the Linux kernel

A race condition was found in the way the Linux kernel’s memory subsystem handled the copy-on-write (COW) breakage of private read-only memory mappings.

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.

Centos/Redhat affected versions: 5/6/7
