dirtyfrag (exploit vulnerability)

This issue confirms `dirtyfrag` exploitability on Proxmox kernels, specifically `7.0.0-3-pve`. The successful privilege escalation from `testuser` to `root` demonstrates a critical vulnerability in a widely used virtualization platform. This has significant market implications for infrastructure security. Proxmox users, often managing critical virtualized environments, face direct risk. SaaS security vendors must prioritize detection and mitigation for such vulnerabilities in hypervisor-level systems. The ability to compromise the host system via a guest or local user is a high-severity event, driving demand for robust security solutions capable of protecting virtualized infrastructure.
