rust-vmm — Vulnerabilities & Security Advisories 3

Rust-vmm is a Rust framework for developing virtual machine monitors (VMMs) and hypervisors, primarily used in cloud infrastructure and virtualization environments. Historically, it has been susceptible to memory corruption vulnerabilities, including buffer overflows and use-after-free issues, which could lead to remote code execution or privilege escalation. The project maintains memory safety through Rust's ownership model, but legacy C code integrations have introduced risks. Three CVEs have been recorded, including one allowing guest-to-host escape via improper input validation. While the framework emphasizes security through compile-time checks, its complexity and integration with other components remain potential attack surfaces.
