Description Prasad J Pandit 2016-06-08 09:57:06 UTC
Quick Emulator(Qemu) built with the MegaRAID SAS 8708EM2 Host Bus Adapter
emulation support is vulnerable to an information leakage issue. It
could occur while processing MegaRAID Firmware Interface(MFI) command to read
device control information in 'megasas_ctrl_get_info'.

A privileged user inside guest could use this flaw to leak host memory bytes.
