The vulnerability of the sm501_2d_operation function in the QEMU hardware emulation software, located in the sm501.c file, involves integer overflows, which allow attackers to compromise data integrity.

The vulnerability of the sm5012doperation function in the QEMU hardware emulation software, located in the sm501.c file, is related to integer overflows. Exploiting this vulnerability could allow an attacker to compromise data integrity...

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.
