CVE-2010-4527

Description

From CVE.org

The load_mixer_volumes function in sound/oss/soundcard.c in the OSS sound subsystem in the Linux kernel before 2.6.37 incorrectly expects that a certain name field ends with a '\0' character, which allows local users to conduct buffer overflow attacks and gain privileges, or possibly obtain sensitive information from kernel memory, via a SOUND_MIXER_SETLEVELS ioctl call.

Statement

Not vulnerable. This issue did not affect the versions of Linux kernel as shipped with Red Hat Enterprise Linux 4, 5, 6 and Red Hat Enterprise MRG as they did not provide support for Open Sound System (OSS).

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).
