CVE-2016-4454 is a medium-severity vulnerability rated 6/10 on the CVSS scale. The vmsvga_fifo_read_raw function in hw/display/vmware_vga.c in QEMU allows local guest OS administrators to obtain sensitive host memory information or cause a denial of service (QEMU process crash) by changing FIFO registers and issuing a VGA command, which triggers an out-of-bounds read.. EPSS estimates a 0.43% chance of exploitation in the next 30 days.
