Vulnerability Summary for CVE-2012-4542

Original release date: 02/28/2013
Last revised: 06/20/2013
Source: US-CERT/NIST

Overview

block/scsi_ioctl.c in the Linux kernel through 3.8 does not properly consider the SCSI device class during authorization of SCSI commands, which allows local users to bypass intended access restrictions via an SG_IO ioctl call that leverages overlapping opcodes.

Impact

CVSS Severity (version 2.0):
CVSS v2 Base Score: 4.6 (MEDIUM) (AV:L/AC:L/Au:N/C:P/I:P/A:P) (legend)
Impact Subscore: 6.4
Exploitability Subscore: 3.9
CVSS Version 2 Metrics:
Access Vector: Locally exploitable
Access Complexity: Low
Authentication: Not required to exploit
Impact Type: Allows unauthorized disclosure of information; Allows unauthorized modification; Allows disruption of service
