CVE-2010-0415
Description
From CVE.org
The do_pages_move function in mm/migrate.c in the Linux kernel before 2.6.33-rc7 does not validate node values, which allows local users to read arbitrary kernel memory locations, cause a denial of service (OOPS), and possibly have unspecified other impact by specifying a node that is not part of the kernel's node set.
Statement
This issue did not affect the versions of Linux kernel as shipped with Red Hat Enterprise Linux 3 and 4, as they do not include support for sys_move_pages. It was only introduced in kernel version 2.6.18 onwards. This issue was addressed in Red Hat Enterprise Linux 5 and Red Hat Enterprise MRG via https://rhn.redhat.com/errata/RHSA-2010-0147.html and https://rhn.redhat.com/errata/RHSA-2010-0161.html.

Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
