Description Petr Matousek 2010-11-01 21:25:43 UTC

Description of problem:
The SNDRV_HDSP_IOCTL_GET_CONFIG_INFO ioctl in hdsp.c allows
unprivileged users to read uninitialized kernel stack memory, because
several fields of the hdspm_config_info structs declared on the stack
are not altered or zeroed before being copied back to the user.

This issue did not affect the version of Linux kernel as shipped with Red Hat Enterprise Linux 3 as it did not include support for RME Hammerfall DSP Audio.
