Local Privileged Attacker Causes Partial Denial of Service in Oracle VM VirtualBox 7.2.6

Published Apr 21, 2026 CVSS 3.1 · 2.3 Low 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 7.2.6. Easily exploitable vulnerability allows high privileged attacker with logon to the infrastructure where Oracle VM VirtualBox executes to compromise Oracle VM VirtualBox. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Oracle VM VirtualBox. CVSS 3.1 Base Score 2.3 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:L).

Analysis

Technical impact

This vulnerability exists in the core component of Oracle VM VirtualBox version 7.2.6. It permits an attacker who has logged onto the host system with a high‑privileged account to trigger a partial denial of service of the VirtualBox service without requiring user interaction. The flaw causes an availability degradation, does not affect confidentiality or integrity, and is rooted in improper access control (CWE‑284).

Affected Systems

Oracle VM VirtualBox version 7.2.6 is the only documented affected product; no other releases or components are listed.

Risk and Exploitability

The CVSS v3.1 Base Score of 2.3 indicates low severity, while the EPSS score of <1% reflects an extremely low probability of exploitation. The vulnerability is not listed in the CISA KEV catalog. Exploitation requires a local attacker with high‑privilege access to the host, which confines the threat to environments where such accounts exist. Though the risk is low, the availability impact can disrupt operations and warrants timely remediation.

OpenCVE Recommended Actions

Upgrade Oracle VM VirtualBox to a patched version that resolves the denial‑of‑service issue.
Restrict the use of high‑privileged accounts on hosts that run VirtualBox, applying the principle of least privilege.
If VirtualBox is not required to run dynamically, consider disabling or sandboxing the VirtualBox service to reduce the attack surface.
