CVE-2016-7995

CWE-772Published: December 10, 2016· Updated: Jun 17, 2026

6.0

CVSS v3.1

Official Description

Memory leak in the ehci_process_itd function in hw/usb/hcd-ehci.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (memory consumption) via a large number of crafted buffer page select (PG) indexes.

Technical Analysis

CVE-2016-7995 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires high privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in availability disruption (denial of service), with a CVSS base score of 6.0.

The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
