CVE-2020-2725

Low-privilege hypervisor crash or hang

Published Jan 15, 2020 · Updated Sep 30, 2024

Denial of service in Oracle VM VirtualBox Core before 5.2.36, before 6.0.16, and before 6.1.2 allows local users to crash or hang the hypervisor. Oracle has not published the affected Core function or the operation that mishandles attacker-controlled input. A low-privileged account on the host is required; successful exploitation causes only a hang or frequently repeatable crash, with no disclosed data exposure or modification.
