CVE-2012-0879
Description
From CVE.org
The I/O implementation for block devices in the Linux kernel before 2.6.33 does not properly handle the CLONE_IO feature, which allows local users to cause a denial of service (I/O instability) by starting multiple processes that share an I/O context.
Statement
This issue affects the Linux kernel as shipped with Red Hat Enterprise Linux 6. This issue does not affect the Linux kernel as shipped with Red Hat Enterprise Linux 4 and 5 as they did not provide support for CLONE_IO. This issue does not affect the Linux kernel as shipped with Red Hat Enterprise MRG as they already contain the fix. This has been addressed in Red Hat Enterprise Linux 6 via https://rhn.redhat.com/errata/RHSA-2012-0481.html.
Common Vulnerability Scoring System (CVSS) Score Details
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).
