CVE-2020-24352
First published: Tue Jun 16 2020(Updated: )
An issue was discovered in QEMU through 5.1.0. An out-of-bounds memory access was found in the ATI VGA device implementation. This flaw occurs in the ati_2d_blt() routine in hw/display/ati_2d.c while handling MMIO write operations through the ati_mm_write() callback. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service.
