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 ability to cause a partial denial of service (partial DOS) of Oracle VM VirtualBox. CVSS 3.1 Base Score 3.2 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:N/I:N/A:L).
AnalysisAI
Oracle VM VirtualBox 7.2.16 contains a flaw in the Core component that lets a high-privileged attacker who already has a logon on the host trigger a partial denial of service against the VirtualBox process itself. The attack is local (AV:L) and requires elevated privileges (PR:H), but carries a scope change (S:C), meaning the successful exploit can significantly affect additional products layered on the same infrastructure. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires a high-privileged attacker with an interactive logon to the infrastructure where Oracle VM VirtualBox 7.2.16 executes (CVSS AV:L with PR:H), so the attacker must already control an administrative or equivalent account on the VirtualBox host; no user interaction is needed (UI:N). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector AV:L/AC:L/PR:H/UI:N/S:C/C:N/I:N/A:L is internally consistent with the description: an attacker needs an existing high-privileged logon on the machine that runs VirtualBox, no user interaction is required, and the only impact is partial availability loss. … 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 fixed VirtualBox build referenced in Oracle's Critical Patch Update advisory at https://www.oracle.com/security-alerts/cspusep2026.html - the input data names 7.2.16 as the vulnerable version but does not specify the exact patched release number, so obtain the corrected build from Oracle rather than assuming a version. … Detailed patch versions, workarounds, and compensating controls in full report. |
