CVE-2010-3084
Description
From CVE.org
Buffer overflow in the niu_get_ethtool_tcam_all function in drivers/net/niu.c in the Linux kernel before 2.6.36-rc4 allows local users to cause a denial of service or possibly have unspecified other impact via the ETHTOOL_GRXCLSRLALL ethtool command.
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 the Neptune Ethernet driver. It did not affect Red Hat Enterprise Linux 5 and Red Hat Enterprise MRG, as they do not contain the upstream commit 2d96cf8c that introduced this flaw.
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).

Understanding the Weakness (CWE)
Integrity,Confidentiality,Availability
Technical Impact: Read Memory; Modify Memory; Execute Unauthorized Code or Commands
Buffer overflows often can be used to execute arbitrary code, which is usually outside the scope of a program's implicit security policy. This can often be used to subvert any other security service.
Availability
Technical Impact: Modify Memory; DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU)
Buffer overflows generally lead to crashes. Other attacks leading to lack of availability are possible, including putting the program into an infinite loop.
