CVE-2011-2898
Description
From CVE.org
net/packet/af_packet.c in the Linux kernel before 2.6.39.3 does not properly restrict user-space access to certain packet data structures associated with VLAN Tag Control Information, which allows local users to obtain potentially sensitive information via a crafted application.
Statement
This issue did not affect the versions of Linux kernel as shipped with Red Hat Enterprise Linux 4 and 5 as they did not backport the upstream commit 393e52e3 that introduced this flaw. This has been addressed in Red Hat Enterprise Linux 6, and Red Hat Enterprise MRG via https://rhn.redhat.com/errata/RHSA-2011-1350.html and https://rhn.redhat.com/errata/RHSA-2012-0010.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).
