CVE-2026-35248 affects Oracle VM VirtualBox 7.2.6 and involves a difficult to exploit vulnerability that requires a high privileged attacker with logon access to the infrastructure where VirtualBox runs. The vulnerability impacts confidentiality, integrity, and availability by allowing unauthorized modification and partial denial of service of VirtualBox accessible data. The CVSS vector indicates local attack vector, high attack complexity, high privileges required, no user interaction, scope change, and low impact on confidentiality, integrity, and availability. The vulnerability may also affect additional products due to scope change. Oracle's April 2026 Critical Patch Update advisory mentions many patches but does not explicitly confirm a patch for this specific CVE. Oracle strongly recommends applying all relevant patches promptly.

Successful exploitation can lead to unauthorized read and write access to some data accessible by Oracle VM VirtualBox and can cause a partial denial of service affecting the availability of VirtualBox. The vulnerability requires high privileges and local access, limiting the attack surface. There are no known exploits in the wild at this time. The scope of impact extends beyond VirtualBox to other products due to the nature of the vulnerability.
