From ${URL} :

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.
