NCSC-2026-0452 Vulnerabilities fixed in FreeBSD bhyve hypervisor
FreeBSD patched multiple vulnerabilities in the bhyve hypervisor affecting USB 3, audio, and framebuffer device models. The issues stem from race conditions, missing validation, and synchronization problems that could allow a malicious guest virtual machine to crash the hypervisor process or execute arbitrary code in host userspace.
Why it matters: Administrators running FreeBSD with bhyve virtualization must patch immediately, as guest virtual machines can escape to the host and compromise the entire system.
