Technical Summary
CVE-2026-71139 is a vulnerability in the core component of Oracle VM VirtualBox version 7.2.14. It allows a high privileged attacker with local logon access to cause a hang or repeated crash of the VirtualBox application, resulting in a denial of service. The CVSS 3.1 vector indicates low attack vector (local), low attack complexity, high privileges required, no user interaction, unchanged scope, no confidentiality or integrity impact, and high availability impact. The vulnerability affects multiple specific versions of VirtualBox, primarily various Debian/Ubuntu package builds from versions 5.0.4-dfsg-2 through 7.2.6-dfsg-4. The vendor advisory from Oracle references a Critical Security Patch Update released in August 2026 covering many products including Oracle VM VirtualBox version 7.2.14, but does not explicitly confirm patch availability or remediation details for this specific CVE in the provided content.
Potential Impact
Successful exploitation allows a high privileged local attacker to cause a denial of service by hanging or crashing Oracle VM VirtualBox. There is no impact on confidentiality or integrity. The impact is limited to availability disruption of the VirtualBox service.
Mitigation Recommendations
Patch status is not yet confirmed — check the Oracle advisory at https://www.oracle.com/security-alerts/cspuaug2026.html for current remediation guidance.
