CVE-2026-71136

Local high-privilege data access and crash

Published Aug 18, 2026 · Updated Aug 19, 2026

Improper access control in Oracle VM VirtualBox 7.2.14 allows local users to read and modify data and cause repeated crashes. Oracle and NVD identify the flaw only as a Core issue and a CWE-284 access-control problem; neither source discloses the affected function, boundary, or operation performed on untrusted input. Exploitation requires high-privilege logon on the host running VirtualBox, so exposure is limited to post-compromise or privileged local access, with impact bounded to partial data disclosure and modification plus denial of service.
