CVE-2024-21106

Low-privilege denial of service via undisclosed Core flaw

Published Apr 16, 2024 · Updated Aug 26, 2025

Denial of service in Oracle VM VirtualBox Core before 7.0.16 allows local users to hang or repeatedly crash the hypervisor. Oracle has not disclosed the affected Core code path or the operation on attacker-controlled input that triggers the failure. A low-privileged account with logon access to the host infrastructure is required, and successful exploitation interrupts VirtualBox availability without reported data disclosure or modification.
