NVD Description

Note: Versions mentioned in the description apply only to the upstream qemu-kvm package and not the qemu-kvm package as distributed by SLES. See How to fix? for SLES:15.3 relevant fixed versions and status.

An out-of-bounds memory access flaw was found in the ATI VGA device emulation of QEMU. This flaw occurs in the ati_2d_blt() routine while handling MMIO write operations when the guest provides invalid values for the destination display parameters. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service.
