Detailsinfo

A vulnerability, which was classified as problematic, was found in Linux Kernel 2.6.16.9 (Operating System). Affected is the function uart_get_count. The manipulation with an unknown input leads to a information disclosure vulnerability. CWE is classifying the issue as CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. This is going to have an impact on confidentiality. CVE summarizes:

The uart_get_count function in drivers/serial/serial_core.c in the Linux kernel before 2.6.37-rc1 does not properly initialize a certain structure member, which allows local users to obtain potentially sensitive information from kernel stack memory via a TIOCGICOUNT ioctl call.

The issue has been introduced in 03/20/2006. The weakness was published 11/29/2010 by Dan Rosenberg as Bug 648660 as not defined bug report (Bugzilla). The advisory is shared for download at bugzilla.redhat.com. This vulnerability is traded as CVE-2010-4075 since 10/25/2010. The attack needs to be approached locally. The exploitation doesn't require any form of authentication. Technical details and a public exploit are known. The MITRE ATT&CK project declares the attack technique as T1592.

The exploit is shared for download at packetstormsecurity.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1715 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 52739 (Ubuntu 9.10 : linux, linux-ec2 vulnerabilities (USN-1089-1)), which helps to determine the existence of the flaw in a target environment.
