CVE-2024-51565

The hda driver in the bhyve hypervisor is vulnerable to a buffer over-read caused by a guest-controlled value. This flaw allows a malicious guest virtual machine to perform a denial of service (DoS) attack against the bhyve host and potentially read memory within the bhyve process that should be ...

CVE-2024-51562

The bhyve hypervisor is vulnerable to a buffer over-read in the nvme_opc_get_log_page function of the NVMe driver . This flaw stems from a guest-controlled value , which could allow a malicious guest virtual machine to perform a denial of service (DoS) attack against the host or read restricted m...

CVE-2024-41721 bhyve(8) out-of-bounds read access via XHCI emulation

An insufficient boundary validation in the USB code could lead to an out-of-bounds read on the heap, which could potentially lead to an arbitrary write and remote code execution...

CVE-2024-41721 bhyve(8) out-of-bounds read access via XHCI emulation

CVE-2024-32668 bhyve(8) privileged guest escape via USB controller

An insufficient boundary validation in the USB code could lead to an out-of-bounds write on the heap, with data controlled by the caller. A malicious, privileged software running in a guest VM can exploit the vulnerability to achieve code execution on the host in the bhyve userspace process, whic...

FreeBSD -- bhyve(8) privileged guest escape via USB controller

Problem Description: bhyve can be configured to emulate devices on a virtual USB controller XHCI, such as USB tablet devices. An insufficient boundary validation in the USB code could lead to an out-of-bounds write on the heap, with data controlled by the caller. Impact: A malicious, privileged...

FreeBSD : FreeBSD -- Missing error handling in bhyve(8) device models (a6d5d4c1-0564-11ec-b69d-4062311215d5)

Certain VirtIO-based device models failed to handle errors when fetching I/O descriptors. Such errors could be triggered by a malicious guest. As a result, the device model code could be tricked into operating on uninitialized I/O vectors, leading to memory corruption. Impact : A malicious guest...

FreeBSD : FreeBSD -- bhyve(8) virtual machine escape (e722e3c6-bbee-11e6-b1cf-14dae9d210b8)

The bounds checking of accesses to guest memory greater than 4GB by device emulations is subject to integer overflow. Impact : For a bhyve virtual machine with more than 3GB of guest memory configured, a malicious guest could craft device descriptors that could give it access to the heap of the...
