Detailsinfo

A vulnerability, which was classified as problematic, has been found in Intel TDX Module up to 1.4. Affected by this issue is an unknown code block. The manipulation with an unknown input leads to a uninitialized variable vulnerability. Using CWE to declare the problem leads to CWE-457. The code uses a variable that has not been initialized, leading to unpredictable or unintended results. Impacted is confidentiality. CVE summarizes:

Use of uninitialized variable for some TDX Module before version tdx1.5 within Ring 0: Hypervisor may allow an information disclosure. Authorized adversary with a privileged user combined with a high complexity attack may enable data exposure. This result may potentially occur via local access when attack requirements are present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (high), integrity (none) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.

The advisory is shared for download at intel.com. This vulnerability is handled as CVE-2025-32467 since 04/15/2025. The exploitation is known to be difficult.
