Description Andrej Nemec 2016-05-16 14:27:30 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 looking up MegaRAID Firmware Interface(MFI) command frames in 'megasas_lookup_frame' routine.

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