CVE-2020-12829 (GCVE-0-2020-12829)

Vulnerability from cvelistv5 – Published: 2020-08-31 14:41 – Updated: 2024-08-04 12:04
VLAI?
Summary
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.
Severity ?
