CVE-2025-30513 identifies a race condition vulnerability within the Trusted Domain Extensions (TDX) Module, which operates at the hypervisor level (Ring 0) on Intel platforms. The TDX Module is designed to provide hardware-based isolation for virtual machines, enhancing security by isolating workloads. However, this vulnerability allows a system software adversary who already has privileged user access on the host to exploit a timing flaw (race condition) in the TDX Module, enabling escalation of privilege beyond their current level. The attack complexity is low, meaning it does not require sophisticated techniques, but it does require local access and privileged user rights. No user interaction is needed, and no special internal knowledge beyond privileged access is required. The vulnerability impacts confidentiality and integrity severely, potentially allowing unauthorized disclosure or modification of sensitive data or system state within the TDX environment. Availability is not impacted. The CVSS 4.0 score of 8.4 reflects the high severity due to the combination of high confidentiality and integrity impact, low attack complexity, and no user interaction. Although no exploits are known in the wild yet, the vulnerability poses a significant risk to environments relying on TDX for secure virtualization, especially in multi-tenant or cloud scenarios. The vulnerability was reserved in April 2025 and published in February 2026, with affected versions detailed in official advisories. No patches or mitigations are linked in the provided data, indicating organizations must monitor vendor updates closely.

For European organizations, the impact of CVE-2025-30513 is substantial, especially for those utilizing Intel-based virtualization platforms with TDX technology in cloud, data center, or critical infrastructure environments. The vulnerability enables a privileged local attacker to escalate privileges within the hypervisor environment, potentially accessing or modifying sensitive data isolated by TDX protections. This undermines the confidentiality and integrity guarantees of virtualized workloads, which can include sensitive government, financial, healthcare, or industrial control data. Although availability is not affected, the breach of confidentiality and integrity can lead to data exfiltration, unauthorized control, or further lateral movement within networks. Organizations relying on multi-tenant cloud services or running sensitive workloads on TDX-enabled platforms face increased risk of insider threats or compromised privileged accounts exploiting this flaw. The lack of required user interaction and low attack complexity increase the likelihood of exploitation once local privileged access is obtained. This could also impact compliance with European data protection regulations such as GDPR if sensitive personal data is exposed.

To mitigate CVE-2025-30513, European organizations should take the following specific actions: 1) Immediately identify and inventory all systems running Intel TDX-enabled platforms and verify the versions of the TDX Module in use. 2) Monitor Intel’s official security advisories and apply patches or firmware updates as soon as they become available, as no patches are currently linked. 3) Restrict and monitor privileged user access rigorously to minimize the risk of local adversaries gaining the necessary privileges to exploit this vulnerability. 4) Employ enhanced logging and anomaly detection focused on hypervisor and TDX module activities to detect potential exploitation attempts. 5) Consider isolating critical workloads in environments without TDX or with alternative security mechanisms until patches are applied. 6) Use hardware-based security features and virtualization security best practices to reduce the attack surface, such as secure boot, measured boot, and strong access controls on management interfaces. 7) Conduct regular security audits and penetration testing focusing on privilege escalation vectors within virtualization infrastructure. 8) Educate system administrators and security teams about the vulnerability’s nature and the importance of minimizing privileged user risk. These steps go beyond generic advice by focusing on the unique aspects of TDX and hypervisor-level privilege escalation.
