CVE-2020-12829

Priority
Description
In QEMU through 5.0.0, an integer overflow was found in the SM501 display
driver implementation. This flaw occurs in the COPY_AREA macro while
handling MMIO write operations through the sm501_2d_engine_write()
callback. A local attacker could abuse this flaw to crash the QEMU process
in sm501_2d_operation() in hw/display/sm501.c on the host, resulting in a
denial of service.
