Technical Analysis

CVE-2026-47041 is a vulnerability in the core component of Oracle VM VirtualBox, specifically affecting version 7.2.12. It allows a high privileged attacker who has logged on to the infrastructure running Oracle VM VirtualBox to cause a hang or repeated crash, resulting in a complete denial of service. The vulnerability does not impact confidentiality or integrity but affects availability. The scope of the vulnerability extends beyond Oracle VM VirtualBox, potentially impacting additional products. The CVSS 3.1 vector is AV:L/AC:L/PR:H/UI:N/S:C/C:N/I:N/A:H, reflecting local attack vector, low complexity, high privileges required, no user interaction, scope change, no confidentiality or integrity impact, and high availability impact.

Potential Impact

Successful exploitation results in a denial of service condition causing Oracle VM VirtualBox to hang or crash repeatedly. This impacts the availability of the virtualization environment. There is no impact on confidentiality or integrity. The vulnerability requires high privileges and local access to the infrastructure where Oracle VM VirtualBox runs.

Mitigation Recommendations

No patch or official fix information is provided in the available data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, limit access to Oracle VM VirtualBox infrastructure to trusted, high privileged users only to reduce risk.
