CVE-2026-87274

Published Sep 15, 2026 CVSS 3.1 · 4.4 Medium EPSS < 1% KEV · Not listed

Description

Vulnerability in the Oracle VM VirtualBox product of Oracle Virtualization (component: Core). The supported version that is affected is 7.2.16. Difficult to exploit vulnerability allows low privileged attacker with logon to the infrastructure where Oracle VM VirtualBox executes to compromise Oracle VM VirtualBox. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle VM VirtualBox. CVSS 3.1 Base Score 4.4 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:N/I:N/A:H).

Analysis

Technical impact

The vulnerability enables a low‑privileged user with logged‑on access to the host running Oracle VM VirtualBox to initiate a crash of the virtualization engine. Once the fault is triggered through a user‑action, the VirtualBox process repeatedly hangs or exits, effectively denying service to all virtual machines and host applications that depend on it. This is a classic resource exhaustion flaw (CWE‑400).

Affected Systems

Oracle VirtualBox version 7.2.16 is affected. No other product versions were listed as vulnerable.

Risk and Exploitability

The CVSS score of 4.4 indicates a medium severity with a significant Availability impact. The EPSS score of less than 1% suggests a low likelihood of exploitation in the wild at the time of analysis. Attacks require low‑privileged local access and a human‑initiated action; the flaw can be used to disrupt the VirtualBox host service, which may impact many dependent virtual machines.

Affected Products

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

Install the latest Oracle VirtualBox patch (at least version 7.2.17).
Limit local user privileges on the host to only those required for VirtualBox operation.
Enforce strict access controls to the VirtualBox executables and configuration files.
Enable host firewall rules to prevent unauthorized scripts from invoking VirtualBox interfaces.
Monitor VirtualBox logs for repeat crash events and investigate suspicious activity.
