CVE-2024-32668: Freebsd

High severity, CVSS 8.2. EPSS: 0.2% chance of exploitation in the next 30 days.

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, 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.

Affected products

• Freebsd Freebsd: from 13.0, before 13.3 (fixed in 13.3); version 13.3 only; version 13.4 only; version 14.0 only; version 14.1 only
