CVE-2024-21103

Local low-privilege hypervisor takeover

Published Apr 16, 2024 · Updated Mar 13, 2025

Improper access control in Oracle VM VirtualBox Core before 7.0.16 allows local users to take over the hypervisor on Linux hosts. Oracle identifies the affected locus only as the Core component and has not published the operation that mishandles access. Exploitation requires a low-privileged account with logon access to the host; success compromises the VirtualBox security authority and its data, behavior, and availability.
