Description Prasad Pandit 2017-06-07 09:15:24 UTC 
Quick Emulator(Qemu) built with the MegaRAID SAS 8708EM2 Host Bus Adapter
emulation support is vulnerable to a null pointer dereference issue. It
could occur while processing megasas commands via megasas_command_complete().

A privileged user inside guest could use this flaw to crash the Qemu process
on the host resulting in DoS.
