CVE-2013-2140: Input Validation
Published Jun 5, 2013
·Updated
If a system admin provides a disk (which supports the discard aka TRIM or SCSI UNMAP) to a guest as read-only - there are no checks done.
A privileged guest user could use this flaw to destroy data on the disk to which he otherwise wouldn't have write access to.

Other sources
The dispatchdiscardio function in drivers/block/xen-blkback/blkback.c in the Xen blkback implementation in the Linux kernel before 3.10.5 allows guest OS users to cause a denial of service (data loss) via filesystem write operations on a read-only disk that supports the (1) BLKIFOPDISCARD (aka discard or TRIM) or (2) SCSI UNMAP feature.

CVE-2013-2140 affects Linux systems running specific versions of the Linux kernel prior to version 3.10.5.
4
Can CVE-2013-2140 be exploited remotely?
CVE-2013-2140 requires local access to the guest system for exploitation, therefore, it is not a remote vulnerability.
5
What is the impact of exploiting CVE-2013-2140?
Exploiting CVE-2013-2140 can lead to unauthorized data destruction on disks that are configured as read-only for guest users.
