Detailsinfo

A vulnerability classified as critical has been found in Linux Kernel up to 2.6.23 (Operating System). This affects an unknown function of the file drivers/media/video/videobuf-vmalloc.c. The manipulation with an unknown input leads to a memory corruption vulnerability (Leak). CWE is classifying the issue as 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. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

drivers/media/video/videobuf-vmalloc.c in the Linux kernel before 2.6.24 does not initialize videobuf_mapping data structures, which allows local users to trigger an incorrect count value and videobuf leak via unspecified vectors, a different vulnerability than CVE-2010-5321.

The bug was discovered 12/08/2007. The weakness was published 04/24/2017 (Website). The advisory is shared at linuxgrill.com. This vulnerability is uniquely identified as CVE-2007-6761 since 04/23/2017. An attack has to be approached locally. The successful exploitation requires a authentication. Technical details are known, but no exploit is available.

The vulnerability was handled as a non-public zero-day exploit for at least 3425 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 252229 (Linux Distros Unpatched Vulnerability : CVE-2010-5321), which helps to determine the existence of the flaw in a target environment.
