Description

An integer overflow issue was found in the vmxnet3 NIC emulator of the QEMU for versions up to v5.2.0. It may occur if a guest was to supply invalid values for rx/tx queue size or other NIC parameters. A privileged guest user may use this flaw to crash the QEMU process on the host resulting in DoS scenario. An integer overflow flaw was found in the vmxnet3 NIC emulator of QEMU. This issue occurs when a guest supplies invalid values for the rx/tx queue size or other NIC parameters. This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a denial of service.
