Description Prasad J Pandit 2017-02-01 10:29:49 EST 
Quick Emulator(Qemu) built with the MegaRAID SAS 8708EM2 Host Bus Adapter
emulation support is vulnerable to a memory leakage issue. It could occur
while processing MegaRAID Firmware Interface(MFI) command in
'megasas_handle_dcmd' routine.

A privileged user inside guest could use this flaw to leak host memory
resulting DoS issue.
