A vulnerability, which was classified as critical, has been found in Linux Kernel 2.6.16.9 (Operating System). This issue affects the function asihpi_hpi_ioctl. The manipulation with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

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.

The issue has been introduced in 03/20/2006. The weakness was disclosed 05/03/2011 by Dan Rosenberg as confirmed git commit (GIT Repository). It is possible to read the advisory at git.kernel.org. The identification of this vulnerability is CVE-2011-1169 since 03/03/2011. Attacking locally is a requirement. No form of authentication is needed for a successful exploitation. Technical details of the vulnerability are known, but there is no available exploit.

The vulnerability was handled as a non-public zero-day exploit for at least 1870 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 55454 (Ubuntu 10.10 : linux vulnerabilities (USN-1160-1)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Ubuntu Local Security Checks.
