CVE-2026-71128: Medium severity Oracle Oracle VM VirtualBox vulnerability
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).

Event History
Frequently Asked Questions
Who is realistically exposed to this issue?
Systems running the affected supported Oracle VM VirtualBox version 7.2.14 are exposed when an attacker already has high privileges and can log on to the infrastructure where VirtualBox executes. The attack is local and requires no user interaction.
What could an attacker achieve?
A successful attack can cause Oracle VM VirtualBox to hang or repeatedly crash, resulting in a complete denial of service. Because the vulnerability has scope change, the impact may significantly affect additional products.
Does exploitation require prior access or elevated privileges?
Yes. The attacker must have logon access to the infrastructure running Oracle VM VirtualBox and must be highly privileged; the CVSS vector specifies local access and high privileges required.
