CVE-2024-41928: bhyve(8) privileged guest escape via TPM device passthrough
First published: Thu Sep 05 2024(Updated: )
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 process.
