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 trigger a complete denial-of-service condition - causing a hang or frequently repeatable crash of the hypervisor - with a confirmed scope change that can significantly impact additional products beyond VirtualBox itself, likely the host operating system or co-resident guest VMs. The vulnerability is exploitable by an attacker with administrator-level access already present on the host infrastructure, making it most relevant in multi-tenant or shared virtualization environments where privileged-but-not-hypervisor-owner threat actors are a realistic model. …

Vulnerability AssessmentAI

Exploitation	Exploitation requires an attacker to be locally logged on to the host infrastructure where Oracle VM VirtualBox 7.2.14 executes (AV:L), and to hold high-level privileges on that host (PR:H) - consistent with administrator or root access, not ordinary VM guest user access. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment	The CVSS 3.1 base score of 6.0 reflects a carefully bounded risk profile: local access vector (AV:L), low complexity (AC:L), high privileges required (PR:H), no user interaction (UI:N), scope change (S:C), and high availability impact (A:H) with no confidentiality or integrity 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	The primary remediation is to apply the patch released by Oracle as part of the August 2026 Critical Patch Update (CPU), available via the Oracle security advisory at https://www.oracle.com/security-alerts/cspuaug2026.html. … Detailed patch versions, workarounds, and compensating controls in full report.
