CVE-2025-32467 is a medium-severity information disclosure vulnerability identified in Intel's Trusted Domain Extensions (TDX) Module prior to version tdx1.5. The flaw stems from the use of an uninitialized variable within the Ring 0 hypervisor environment, which can lead to leakage of sensitive information from the hypervisor memory space. The vulnerability requires an attacker to have privileged user access on the local system, combined with a high complexity attack vector, but does not require user interaction or special internal knowledge. The attack vector is local, meaning remote exploitation is not feasible. The vulnerability impacts confidentiality by potentially exposing sensitive data but does not compromise system integrity or availability. The CVSS 4.0 vector (AV:L/AC:H/PR:H/UI:N/VC:H/VI:N/VA:N) reflects that the attack requires local access with high privileges and high complexity, no user interaction, and results in high confidentiality impact only. No known exploits have been reported in the wild to date. The vulnerability affects systems running Intel TDX Modules before version tdx1.5, which are used to enhance security in virtualized environments by isolating guest virtual machines. This flaw could undermine the confidentiality guarantees of such environments if exploited. Intel and ecosystem partners are expected to release patches or mitigations to address this issue.

For European organizations, the primary impact of CVE-2025-32467 is the potential exposure of sensitive information within virtualized environments that utilize Intel's TDX technology. This could affect cloud service providers, data centers, and enterprises relying on Intel TDX for workload isolation and confidentiality. Although the vulnerability does not affect system integrity or availability, the confidentiality breach could lead to unauthorized disclosure of sensitive data, intellectual property, or cryptographic keys, which may have regulatory and compliance implications under GDPR and other data protection laws. The requirement for privileged local access limits the attack surface, but insider threats or compromised privileged accounts could exploit this vulnerability. The medium severity rating suggests a moderate risk level, but organizations with high-value or sensitive workloads should treat this vulnerability seriously. The absence of known exploits reduces immediate risk but does not eliminate the need for proactive mitigation.

European organizations should implement the following specific mitigation steps: 1) Inventory and identify all systems running Intel TDX Modules prior to version tdx1.5 to understand exposure. 2) Apply vendor-supplied patches or firmware updates as soon as they become available to remediate the uninitialized variable flaw. 3) Restrict and monitor privileged user access rigorously, employing least privilege principles and strong authentication mechanisms to reduce the risk of local exploitation. 4) Employ runtime monitoring and anomaly detection to identify suspicious privileged activity that could indicate exploitation attempts. 5) Harden hypervisor and host OS configurations to minimize attack surface, including disabling unnecessary services and interfaces. 6) Conduct regular security audits and penetration testing focused on virtualization security to detect potential weaknesses. 7) Maintain up-to-date incident response plans that include scenarios involving insider threats and hypervisor-level compromises. These targeted actions go beyond generic advice by focusing on the specific conditions and environment of the vulnerability.
