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 contains a local privilege-escalation-to-DoS flaw in the Core component that allows a highly privileged host user to repeatedly crash or hang the hypervisor, with scope change meaning hosted guest VMs are also disrupted. The attack requires local logon and high privileges on the host infrastructure, substantially limiting the attacker pool to insiders or already-compromised privileged accounts. …

Vulnerability AssessmentAI

Exploitation	Exploitation requires local logon access to the host infrastructure where Oracle VM VirtualBox 7.2.14 executes AND high privileges on that host (administrator on Windows or root/equivalent on Linux/macOS). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment	The CVSS 3.1 base score of 6.0 reflects a constrained risk profile: local attack vector, high privilege requirement, and purely availability impact. … 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 August 2026 Critical Security Patch Update at https://www.oracle.com/security-alerts/cspuaug2026.html for the patched release; a specific fixed version number is not independently confirmed in the available data beyond the indication that 7.2.14 is affected. … Detailed patch versions, workarounds, and compensating controls in full report.
