CVE-2011-1169

Published: 03 May 2011

Array index error in the asihpi_hpi_ioctl function in sound/pci/asihpi/hpioctl.c in the AudioScience HPI driver in the Linux kernel before 2.6.38.1 might allow local users to cause a denial of service (memory corruption) or possibly gain privileges via a crafted adapter index value that triggers access to an invalid kernel pointer.

From the Ubuntu security team

Dan Rosenberg discovered that some ALSA drivers did not correctly check the adapter index during ioctl calls. If this driver was loaded, a local attacker could make a specially crafted ioctl call to gain root privileges.
