CVE-2023-21989

Privileged disclosure via undisclosed Core flaw

Published Apr 18, 2023 · Updated Sep 16, 2024

Information disclosure in Oracle VM VirtualBox before 6.1.44 and before 7.0.8 allows local users with high privileges to read accessible data. Oracle identifies the Core component but has not published the defective operation or input that triggers the disclosure. Successful exploitation exposes critical or all VirtualBox-accessible data and can cross the product's security scope, without reported modification or interruption.
