CVE-2024-43102 umtx Kernel panic or Use-After-Free

Concurrent removals of certain anonymous shared memory mappings by using the UMTXSHMDESTROY sub-request of UMTXOPSHM can lead to decreasing the reference count of the object representing the mapping too many times, causing it to be freed too early. A malicious code exercizing the UMTXSHMDESTROY...

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...

CVE-2024-45063 Multiple issues in ctl(4) CAM Target Layer

The function ctlwritebuffer incorrectly set a flag which resulted in a kernel Use-After-Free when a command finished processing. Malicious software running in a guest VM that exposes virtioscsi can exploit the vulnerabilities to achieve code execution on the host in the bhyve userspace process,...

CVE-2024-45063

The CVE-2024-45063 issue affects FreeBSD ctl(4) CAM Target Layer. The root cause is that ctl_write_buffer incorrectly sets a flag, causing a kernel Use-After-Free when a command finishes processing. The advisory describes guest VMs exposing virtio_scsi accessing the kernel via bhyve, enabling cod...

CVE-2024-42416 Multiple issues in ctl(4) CAM Target Layer

The ctlreportsupportedopcodes function did not sufficiently validate a field provided by userspace, allowing an arbitrary write to a limited amount of kernel help memory. Malicious software running in a guest VM that exposes virtioscsi can exploit the vulnerabilities to achieve code execution on...

CVE-2024-42416

CVE-2024-42416 affects FreeBSD ctl(4) CAM Target Layer: ctl_report_supported_opcodes did not properly validate a field from userspace, enabling an arbitrary write into limited kernel help memory. Impact: guest VMs using virtio_scsi can abuse this to execute code on the host bhyve process (root), ...

CVE-2024-8178

CVE-2024-8178 affects the FreeBSD ctl subsystem (ctl_write_buffer and ctl_read_buffer) where memory allocated for return to userspace was not initialized, enabling abuse via virtio_scsi in guest VMs. Exploitation could allow code execution on the host bhyve process (typically running as root), wi...

CVE-2024-41928

Malicious software running in a guest VM can exploit the buffer overflow to achieve code execution on the host in the bhyve userspace process, which typically runs as root. Note that bhyve runs in a Capsicum sandbox, so malicious code is constrained by the capabilities available to the bhyve...
