CVE-2025-30725: 
VirtualBox vulnerability analysis and mitigation

A vulnerability has been identified in Oracle VM VirtualBox version 7.1.6 (component: Core). This vulnerability, tracked as CVE-2025-30725, was discovered by Zong Cao of Cyber Security Lab of NTU and disclosed on April 15, 2025. The vulnerability affects Oracle's virtualization product and requires a high-privileged attacker with logon access to the infrastructure where Oracle VM VirtualBox executes (Oracle CPU, NVD).

The vulnerability has been assigned a CVSS 3.1 Base Score of 6.7 (Medium severity) with the following vector: CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:L/I:L/A:H. The technical assessment indicates that this is a difficult-to-exploit vulnerability that requires high privileges and local access, but has the potential for scope change, meaning attacks may significantly impact additional products beyond VirtualBox (NVD).

Successful exploitation of this vulnerability can result in multiple adverse effects: unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle VM VirtualBox, unauthorized update, insert or delete access to some of Oracle VM VirtualBox accessible data, and unauthorized read access to a subset of Oracle VM VirtualBox accessible data (Oracle CPU).

Oracle has addressed this vulnerability in their April 2025 Critical Patch Update. Users are strongly advised to apply the security patches as soon as possible to mitigate the risk of successful attacks (Oracle CPU).
