DescriptionCVE.org

Vulnerability in the Oracle VM VirtualBox product of Oracle Virtualization (component: Core). The supported version that is affected is 7.2.14. Easily exploitable vulnerability allows high privileged attacker with logon to the infrastructure where Oracle VM VirtualBox executes to compromise Oracle VM VirtualBox. While the vulnerability is in Oracle VM VirtualBox, attacks may significantly impact additional products (scope change). 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 6.0 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:N/I:N/A:H).

AnalysisAI

Oracle VM VirtualBox 7.2.14 Core component allows a high-privileged local attacker to cause a complete denial of service - hang or repeatable crash - with a scope change that can impact additional products beyond VirtualBox itself, such as guest virtual machines sharing the same host. The vulnerability is locally-triggered and requires existing privileged access to the infrastructure, limiting opportunistic exploitation. …

Vulnerability AssessmentAI

Exploitation	Exploitation requires an attacker to have already obtained a high-privileged account (PR:H per CVSS) with the ability to log on locally to the physical or virtual infrastructure where Oracle VM VirtualBox 7.2.14 executes (AV:L). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment	The CVSS 3.1 base score of 6.0 (Medium) reflects the constrained attack surface: local access is required (AV:L), complexity is low (AC:L), but the attacker must hold high privileges (PR:H), and impact is limited to availability (C:N/I:N/A:H). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario	Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation	Consult Oracle's Critical Security Patch Update Advisory for August 2026 at https://www.oracle.com/security-alerts/cspuaug2026.html to obtain the patched version of Oracle VM VirtualBox; the exact fixed version number was not independently confirmed in the available intelligence beyond the advisory reference. … Detailed patch versions, workarounds, and compensating controls in full report.
