CVE-2009-3939
Description
From CVE.org
The poll_mode_io file for the megaraid_sas driver in the Linux kernel 2.6.31.6 and earlier has world-writable permissions, which allows local users to change the I/O mode of the driver by modifying this file.
Statement
This issue did not affect the version of the Linux kernel as shipped with Red Hat Enterprise Linux 3, as it does not implement the sysfs file system ("/sys/"), through which poll_mode_io file is exposed by the megaraid_sas driver.
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).
