Description Prasad J Pandit 2014-06-12 09:58:01 EDT
Linux kernel built with the Generic Target Core Mod(TCM), an iSCSI Target
engine(CONFIG_TARGET_CORE), along with the Ramdisk back-end driver support, is vulnerable to an information leakage flaw. It could occur while performing I/O operations on behalf of a SCSI initiator.

A privileged user/process could use this flaw to leak kernel memory bytes.
