CVE-2020-2701

Hypervisor code execution via xHCI heap overflow

Published Jan 15, 2020 · Updated Sep 30, 2024

Heap buffer overflow in Oracle VM VirtualBox Core before 5.2.36, before 6.0.16, and before 6.1.2 allows guest OS users to execute hypervisor code. The xHCI component fails to validate user-supplied data before writing it, allowing a write past the end of an allocated heap buffer. Exploitation requires high-privileged code execution in a guest and can compromise confidentiality, integrity, and availability beyond that guest.
