CVE-2016-5105 is a medium-severity vulnerability rated 4.4/10 on the CVSS scale. The megasas_dcmd_cfg_read function in hw/scsi/megasas.c in QEMU, when built with MegaRAID SAS 8708EM2 Host Bus Adapter emulation support, uses an uninitialized variable, which allows local guest administrators to read host memory via vectors involving a MegaRAID Firmware Interface (MFI) command.. EPSS estimates a 0.41% chance of exploitation in the next 30 days.
