ati-vga in hw/display/ati.c in QEMU 4.2.0 allows guest OS users to trigger infinite recursion via a crafted mm_index value during an ati_mm_read or ati_mm_write call.
An infinite recursion flaw was found in the ati-vga emulator of the QEMU. The issue occurs in ati_mm_read/write routines while accessing VGA registers, for certain values of the 'mm_index' variable. This flaw allows a guest user or process to crash the QEMU process, resulting in a denial of service.
