CVE-2020-2682

Hypervisor code execution via out-of-bounds array access

Published Jan 15, 2020 · Updated Sep 30, 2024

Out-of-bounds access in Oracle VM VirtualBox Core before 5.2.36, before 6.0.16, and before 6.1.2 allows local users to execute hypervisor code. VBoxVHWAHandleTable fails to validate user-supplied data before accessing an allocated array, permitting memory access past its end. Exploitation requires high-privileged code execution in a guest and grants execution in the hypervisor, enabling takeover across the host trust boundary.
