* Multiple out-of-bounds write flaws were found in the way the Cherry Cymotion keyboard driver, KYE/Genius device drivers, Logitech device drivers, Monterey Genius KB29E keyboard driver, Petalynx Maxter remote control driver, and Sunplus wireless desktop driver handled invalid HID reports. An attacker with physical access to the system could use either of these flaws to write data past an allocated memory buffer.
(CVE-2014-3184, Low)

* An information leak flaw was found in the RAM Disks Memory Copy (rd_mcp) back end driver of the iSCSI Target subsystem could allow a privileged user to leak the contents of kernel memory to an iSCSI initiator remote client. (CVE-2014-4027, Low)

* An information leak flaw in the Linux kernel's ALSA implementation could allow a local, privileged user to leak kernel memory to user space. (CVE-2014-4652, Low)
