FKIE_CVE-2016-2392

Vulnerability from fkie_nvd - Published: 2016-06-16 18:59 - Updated: 2026-06-17 00:43
Severity
6.5 (Medium) - CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H
Summary
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.
