CVE-2026-71126

Low-privilege takeover via undisclosed Core flaw

Published Aug 18, 2026 · Updated Aug 25, 2026

Unspecified flaw in Oracle VM VirtualBox Core 7.2.14 allows local users with low privileges to take over the hypervisor. Oracle identifies the affected locus only as Core and has not published the operation that mishandles untrusted input. Exploitation requires local logon and high attack complexity but no user interaction, and successful attacks can cross a security boundary and affect confidentiality, integrity, and availability.
