Low-privilege data disclosure and repeatable service crashes
Published Oct 15, 2024 · Updated Aug 26, 2025
Core flaw in Oracle VM VirtualBox before 7.0.22 and before 7.1.2 allows local users to read data and repeatedly crash the service. Oracle has not published the affected function, input path, or operation in the Core component, so the code-level mechanism remains undisclosed. Low-privileged users with logon access to the host can cause a hang or repeatable crash and read a subset of VirtualBox-accessible data.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=* <7.0.22
- Affected versionversion=* <7.1.2
