CVE-2024-31068 identifies a hardware-level vulnerability in certain Intel processors caused by improper finite state machines (FSMs) within the processor's internal hardware logic. FSMs are critical for managing processor states and transitions; flaws here can lead to unpredictable processor behavior. In this case, a privileged local user—such as an administrator or system process with elevated rights—can exploit this FSM flaw to induce a denial of service (DoS) condition. This DoS could manifest as system hangs, crashes, or processor unavailability, effectively disrupting normal operations. The vulnerability does not require user interaction and does not affect confidentiality or integrity, focusing solely on availability. The CVSS 4.0 vector indicates local attack vector (AV:L), high attack complexity (AC:H), no privileges required (PR:H), no user interaction (UI:N), and high impact on availability (VA:H). No known exploits exist in the wild, and Intel has not yet published patches or microcode updates, though these are expected. The affected processor models and versions are not explicitly listed here but are referenced in Intel advisories. This hardware-level flaw is significant because it cannot be fully mitigated by software alone, requiring microcode or firmware updates. Organizations should prepare to deploy patches and restrict privileged access to minimize risk.

For European organizations, the primary impact of CVE-2024-31068 is the potential for denial of service on systems running affected Intel processors. This could disrupt critical services, especially in data centers, cloud providers, telecommunications, and government infrastructure relying heavily on Intel hardware. While the vulnerability does not expose data or allow privilege escalation, service outages can cause operational downtime, financial losses, and reputational damage. Organizations with stringent uptime requirements or those operating critical infrastructure may face significant challenges if this vulnerability is exploited. The requirement for local privileged access limits remote exploitation risk but does not eliminate insider threat or compromise scenarios where attackers gain elevated access. The absence of known exploits reduces immediate risk but also means organizations must proactively patch once updates are available. The medium severity rating reflects a moderate but non-trivial threat to availability.

Mitigation should focus on multiple layers: 1) Monitor Intel’s security advisories closely and apply microcode or firmware updates as soon as they are released to address the FSM flaw. 2) Restrict and tightly control privileged access on all systems with affected Intel processors to reduce the risk of local exploitation. 3) Implement robust system monitoring and alerting for unusual processor or system behavior indicative of DoS attempts. 4) Use hardware-based security features and virtualization isolation to limit the impact of potential local exploits. 5) Conduct regular security audits and insider threat assessments to detect misuse of privileged accounts. 6) For critical systems, consider redundancy and failover mechanisms to maintain availability in case of DoS events. 7) Coordinate with hardware vendors and service providers to ensure timely patch deployment. These steps go beyond generic advice by emphasizing proactive patch management, access control, and operational resilience.
