Detailsinfo

A vulnerability was found in Linux Kernel 2.6.16.9 (Operating System) and classified as critical. This issue affects the function snd_usb_caiaq_midi_init. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Multiple buffer overflows in the caiaq Native Instruments USB audio functionality in the Linux kernel before 2.6.38-rc4-next-20110215 might allow attackers to cause a denial of service or possibly have unspecified other impact via a long USB device name, related to (1) the snd_usb_caiaq_audio_init function in sound/usb/caiaq/audio.c and (2) the snd_usb_caiaq_midi_init function in sound/usb/caiaq/midi.c.

The issue has been introduced in 03/20/2006. The weakness was presented 02/18/2011 as Bug 677881 as not defined bug report (Bugzilla). It is possible to read the advisory at bugzilla.redhat.com. The identification of this vulnerability is CVE-2011-0712. The exploitation is known to be difficult. 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 pricing for an exploit might be around USD $5k-$25k at the moment (estimation calculated on 10/17/2021).

The vulnerability was handled as a non-public zero-day exploit for at least 1796 days. During that time the estimated underground price was around $5k-$25k.
