"The 7.2.16 versions of VM VirtualBox installed on the remote host are affected by multiple vulnerabilities as
referenced in the October 2026 CPU advisory.

  - 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 low 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
    access to critical data or complete access to all Oracle VM VirtualBox accessible data and unauthorized
    ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle VM VirtualBox.
    (CVE-2026-87301)

    supported version that is affected is 7.2.16. Easily exploitable vulnerability allows low privileged
    attacker with logon to the infrastructure where Oracle VM VirtualBox executes to compromise Oracle VM
    VirtualBox. Successful attacks require human interaction from a person other than the attacker and 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. (CVE-2026-87303)
