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. En QEMU versiones hasta 5.0.0, se encontró un desbordamiento de enteros en la implementación del controlador de pantalla SM501. Este fallo ocurre en la macro COPY_AREA al manejar operaciones de escritura MMIO por medio de la devolución de llamada de sm501_2d_engine_write(). • https://bugzilla.redhat.com/show_bug.cgi?id=1808510 https://usn.ubuntu.com/4467-1 https://www.debian.org/security/2020/dsa-4760 • CWE-190: Integer Overflow or Wraparound •
