EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 5.7 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.1%, top 100% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

Insufficient verification of data authenticity for some Intel(R) Trust Domain Extensions (Intel(R) TDX) within Ring 0: Hypervisor may allow an information disclosure. A system software adversary with a privileged user access combined with a high complexity attack may enable data exposure. This result may potentially occur via local access when attack requirements are present without any user interaction. The potential vulnerability may impact the confidentiality (high), integrity (low) and no effect on availability. Subsequent system impacts include reduced confidentiality (low), integrity (low), and no effect on availability.
