Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.2.2

Description The issue allows local users to bypass intended restrictions on disk read and write operations. This is achieved by sending a SCSI command to either a partition block device or an LVM volume, due to the Linux kernel's failure to properly restrict SG IO ioctl calls.

Recommendations For versions prior to 3.2.2, update to version 3.2.2 or later to resolve the issue. As a temporary workaround, consider restricting access to the SG IO ioctl calls to minimize the risk of exploitation.
