PRIOn knowledge basePRION:CVE-2010-4080Design/Logic Flaw
The snd_hdsp_hwdep_ioctl function in sound/pci/rme9652/hdsp.c in the Linux kernel before 2.6.36-rc6 does not initialize a certain structure, which allows local users to obtain potentially sensitive information from kernel stack memory via an SNDRV_HDSP_IOCTL_GET_CONFIG_INFO ioctl call.
