Description Prasad J Pandit 2017-04-28 11:31:30 UTC
Quick Emulator(Qemu) built with the MegaRAID SAS 8708EM2 Host Bus Adapter
emulation support is vulnerable to an out-of-bounds read access issue. It
could occur while performing a MMIO write operation.

A privileged user inside guest could use this flaw to read host memory
leading to potentially crash the Qemu process on the host.
