CVE-2026-87278: Oracle VM VirtualBox denial of service and data modification in Core

CVE-2026-87278 · Severity: medium · CVSS 6.1 · Published 2026-09-15

Oracle VM VirtualBox is a widely-used virtualization platform that enables organizations to run multiple operating systems on a single computer. This vulnerability allows a local attacker with system access to cause the application to crash or become unresponsive, or to tamper with virtual machine data. While an attacker must interact with a user to exploit this issue, successful attacks can disrupt virtual machine operations and compromise the integrity of hosted systems.
