CVE-2010-4081
First published: Mon Nov 01 2010(Updated: )
Description of problem: The SNDRV_HDSP_IOCTL_GET_CONFIG_INFO ioctl in hdspm.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.
