CVE-2010-4080
Published: 30 November 2010
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.
From the Ubuntu security team
Dan Rosenberg discovered that the RME Hammerfall DSP audio interface driver did not correctly clear kernel memory. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy.
