CVE-2016-2392

MEDIUM

QEMU < 2.5.1 - Denial of Service via USB Net Device Emulator

Title source: llm
STIX 2.1

Description

The is_rndis function in the USB Net device emulator (hw/usb/dev-network.c) in QEMU before 2.5.1 does not properly validate USB configuration descriptor objects, which allows local guest OS administrators to cause a denial of service (NULL pointer dereference and QEMU process crash) via vectors involving a remote NDIS control message packet.
