CVE-2012-6075: Canonical Ubuntu Linux

High severity, CVSS 9.3. EPSS: 4.9% chance of exploitation in the next 30 days.

Buffer overflow in the e1000_receive function in the e1000 device driver (hw/e1000.c) in QEMU 1.3.0-rc2 and other versions, when the SBP and LPE flags are disabled, allows remote attackers to cause a denial of service (guest OS crash) and possibly execute arbitrary guest code via a large packet.
