Last modified
CVE-2012-4542 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.35% chance of exploitation in the next 30 days.
