Detailsinfo

A vulnerability was found in Intel TDX Module up to 1.4. It has been declared as problematic. This vulnerability affects an unknown code block. The manipulation with an unknown input leads to a race condition vulnerability. The CWE definition for the vulnerability is CWE-362. The product contains a code sequence that can run concurrently with other code, and the code sequence requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence that is operating concurrently. As an impact it is known to affect availability. CVE summarizes:

Race condition for some TDX Module before version tdx1.5 within Ring 0: Hypervisor may allow a denial of service. Authorized adversary with a privileged user combined with a high complexity attack may enable denial of service. 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 (none), integrity (none) and availability (high) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (low) impacts.

The advisory is available at intel.com. This vulnerability was named CVE-2025-31944 since 04/15/2025. The exploitation appears to be difficult. Local access is required to approach this attack. Additional levels of successful authentication are necessary for exploitation. The technical details are unknown and an exploit is not available.

Upgrading to version 1.5 eliminates this vulnerability.
