UnknownEPSS 0.57%

Last modified

CVE-2011-4127 is a vulnerability of currently unknown severity. The Linux kernel before 3.2.2 does not properly restrict SG_IO ioctl calls, which allows local users to bypass intended restrictions on disk read and write operations by sending a SCSI command to (1) a partition block device or (2) an LVM volume.. EPSS estimates a 0.57% chance of exploitation in the next 30 days.

Description

The Linux kernel before 3.2.2 does not properly restrict SG_IO ioctl calls, which allows local users to bypass intended restrictions on disk read and write operations by sending a SCSI command to (1) a partition block device or (2) an LVM volume.
