CVE-2026-71136: High 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 as well as unauthorized update, insert or delete access to some of Oracle VM VirtualBox accessible data and unauthorized read access to a subset of Oracle VM VirtualBox accessible data. CVSS 3.1 Base Score 7.3 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:H).

Frequently Asked Questions
Who is realistically exposed to this vulnerability?
Oracle VM VirtualBox deployments running the supported affected version 7.2.14 are exposed. Exploitation requires an attacker to already have high privileges and logon access to the infrastructure where VirtualBox runs, so it is primarily a post-compromise or privileged-insider risk rather than a remote unauthenticated attack.
What level of access does an attacker need to exploit it?
The attacker needs local access and high privileges on the infrastructure hosting Oracle VM VirtualBox. No user interaction is required, and the attack complexity is rated low.
What could a successful attacker do?
A successful attack can hang or repeatedly crash VirtualBox, resulting in complete denial of service. It can also permit unauthorized read access to a subset of VirtualBox-accessible data and unauthorized update, insertion, or deletion of some such data; impacts may extend to additional products because the scope changes.
