    Ziming Zhang discovered that the QEMU OSS audio driver incorrectly handled certain operations. An attacker     inside a guest could possibly use this issue to cause QEMU to crash, resulting in a denial of service.
    This issue only affected Ubuntu 20.04 LTS. (CVE-2020-14415)

    Ziming Zhang discovered that the QEMU XGMAC Ethernet controller incorrectly handled packet transmission.
    An attacker inside a guest could use this issue to cause QEMU to crash, resulting in a denial of service,     or possibly execute arbitrary code. (CVE-2020-15863)

    Ziming Zhang discovered that the QEMU e1000e Ethernet controller incorrectly handled packet processing. An     attacker inside a guest could possibly use this issue to cause QEMU to crash, resulting in a denial of     service. This issue only affected Ubuntu 18.04 LTS and Ubuntu 20.04 LTS.
