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-2024-42416

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-2024-8178 Multiple issues in ctl(4) CAM Target Layer

The ctlwritebuffer and ctlreadbuffer functions allocated memory to be returned to userspace, without initializing it. 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, which...

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...
