Executive Summary

This vulnerability is a divide-by-zero error in the VirtIO network device emulation within BitVisor. It occurs in versions from commit 108df6 (2020-05-20) to commit 480907 (2025-07-06). A local attacker can exploit this by crafting a specific PCI configuration space access, which triggers the divide-by-zero and causes the host hypervisor to crash.

Impact Analysis

The vulnerability can cause a denial of service by crashing the host hypervisor. This means that an attacker with local access could disrupt the operation of the virtualized environment, potentially leading to downtime or loss of availability of services running on the hypervisor.
