3DescriptionNVD
Vulnerability in the Oracle VM VirtualBox product of Oracle Virtualization (component: Core). The supported version that is affected is 7.2.16. 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 read access to a subset of Oracle VM VirtualBox accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Oracle VM VirtualBox. CVSS 3.1 Base Score 4.6 (Confidentiality and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:L/I:N/A:L).
AnalysisAI
A locally exploitable flaw in the Core component of Oracle VM VirtualBox 7.2.16 lets an attacker who already holds a high-privileged logon on the host read a limited subset of VirtualBox-accessible data and trigger a partial denial of service against the hypervisor. The scope-change rating (S:C) indicates the impact can extend beyond VirtualBox itself to other products on or around the host, but exploitation requires local logon with elevated privileges and there is no indication of remote reach. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a high-privileged local logon on the infrastructure where Oracle VM VirtualBox executes, per the CVSS PR:H/AV:L metrics - typically interactive or administrative access to the host operating system, not remote or network access. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 base score of 4.6 (AV:L/AC:L/PR:H/UI:N/S:C/C:L/I:N/A:L) describes a low-complexity but high-privilege local attack with no user interaction required, limited confidentiality loss, and partial availability loss, with a scope change that amplifies consequences outside the vulnerable component. … 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 | Apply the Oracle Critical Patch Update referenced in https://www.oracle.com/security-alerts/cspusep2026.html and upgrade Oracle VM VirtualBox to the patched build released in that update; 7.2.16 is documented as vulnerable, so the fixed version is whatever supersedes it in the 7.2.x line or a later supported train, and that exact version should be confirmed from the advisory rather than assumed. … Detailed patch versions, workarounds, and compensating controls in full report. |
