Introduction

Oracle has released a security update to address a critical vulnerability in Oracle VM VirtualBox. Oracle VM VirtualBox is cross-platform virtualisation software.

CVE-2025-30712 is an 'improper access control' vulnerability with a CVSSv3 score of 8.1 that affects the Oracle Virtualisation component of VirtualBox. Successful exploitation could allow an attacker with administrative privileges to gain linear memory access, leading to arbitrary read/write access in the host memory, enabling virtual machine escape. The attacker could gain unauthorised access to all Oracle VM VirtualBox accessible data or critical data and that could lead to a partial denial-of-service (DoS) attack.
