NVD Description

Note: Versions mentioned in the description apply only to the upstream qemu-arm package and not the qemu-arm package as distributed by SLES. See How to fix? for SLES:15.2 relevant fixed versions and status.

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.
