CVE-2025-22830 is a high-severity vulnerability identified in AMI's AptioV BIOS firmware, specifically version 5.0. The vulnerability is classified under CWE-362, which pertains to race conditions arising from concurrent execution using shared resources without proper synchronization. In this context, a race condition occurs when multiple processes or threads access and manipulate shared resources concurrently, and the timing of their execution leads to unexpected or erroneous behavior. This flaw exists in the BIOS layer, a critical component responsible for initializing hardware and bootstrapping the operating system. Exploitation requires local access with high privileges and partial user interaction, indicating that an attacker must already have significant access to the system. Successful exploitation can cause resource exhaustion, potentially leading to denial of service conditions or corruption of BIOS state. This can impact the confidentiality, integrity, and availability of the system by disrupting normal operations, corrupting firmware settings, or enabling further privilege escalation. The CVSS 4.0 vector indicates low attack complexity but requires privileged access and some user interaction, with high impact on confidentiality, integrity, and availability, and a broad scope affecting system components. Although no known exploits are currently in the wild, the vulnerability's presence in a foundational firmware component makes it a critical concern for system stability and security.

For European organizations, this vulnerability poses significant risks, especially in sectors reliant on high-assurance computing environments such as finance, healthcare, government, and critical infrastructure. BIOS-level vulnerabilities can undermine the trustworthiness of the entire system stack, potentially allowing attackers to bypass OS-level security controls or cause persistent system failures. Resource exhaustion at the BIOS level could lead to system crashes or boot failures, resulting in operational downtime and potential data loss. Confidentiality breaches could arise if the race condition allows manipulation or leakage of sensitive firmware data. Integrity could be compromised if firmware settings or boot processes are altered maliciously. Given the requirement for local privileged access, insider threats or attackers who have already compromised endpoints pose the greatest risk. The lack of known exploits currently provides a window for proactive mitigation, but the high severity score underscores the urgency for European organizations to address this vulnerability to maintain operational resilience and protect sensitive data.

Organizations should prioritize updating to patched versions of the AptioV BIOS firmware once AMI releases a fix, as no patch links are currently available. In the interim, strict access controls should be enforced to limit local administrative privileges to trusted personnel only. Endpoint detection and response (EDR) solutions should be configured to monitor for unusual local privilege escalations or attempts to manipulate BIOS settings. Implementing hardware-based security features such as Trusted Platform Module (TPM) and BIOS write protections can reduce the risk of unauthorized firmware modifications. Regular audits of BIOS configurations and integrity checks using secure boot mechanisms can help detect anomalies early. Additionally, organizations should educate IT staff about the risks of local privilege misuse and enforce policies that minimize unnecessary local access. For environments with high security requirements, consider isolating critical systems physically or logically to reduce exposure to insider threats. Finally, maintain close monitoring of AMI advisories for patch releases and apply updates promptly.
