"The 7.1.14 and 7.2.4 versions of VM VirtualBox installed on the remote host are affected by multiple vulnerabilities as
referenced in the January 2026 CPU advisory.

  - Vulnerability in the Oracle VM VirtualBox product of Oracle Virtualization (component: Core). Supported
    versions that are affected are 7.1.14 and 7.2.4. Difficult to exploit vulnerability allows unauthenticated
    attacker with access to the physical communication segment attached to the hardware where the Oracle VM
    VirtualBox executes to compromise Oracle VM VirtualBox. Successful attacks of this vulnerability can
    result in takeover of Oracle VM VirtualBox. (CVE-2026-21982)

  - Vulnerability in the Oracle VM VirtualBox product of Oracle Virtualization (component: Core). Supported
    versions that are affected are 7.1.14 and 7.2.4. 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 takeover of
    Oracle VM VirtualBox. (CVE-2026-21955, CVE-2026-21956, CVE-2026-21987, CVE-2026-21988, CVE-2026-21990)
