Subject: CVE request Qemu: scsi: mptsas: OOB access when freeing MPTSASRequest
 object

   Hello,

Quick emulator(Qemu) built with the LSI SAS1068 Host Bus emulation support, is 
vulnerable to an invalid memory access issue. It could occur while processing 
scsi io requests in mptsas_process_scsi_io_request.

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