CVE-2012-4542

Linux kernel <3.8 - Privilege Escalation

Title source: llm
STIX 2.1

Description

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.
