CVE-2026-20705 is a medium-severity vulnerability rated 5.3/10 on the CVSS scale. Insecure storage of sensitive information in the Intel(R) TDX module for some Intel(R) platform within Ring 0: Trust Domain may allow information disclosure. System software adversary with a privileged user combined with a high complexity attack may enable data exposure. EPSS estimates a 0.10% chance of exploitation in the next 30 days.

Description

Insecure storage of sensitive information in the Intel(R) TDX module for some Intel(R) platform within Ring 0: Trust Domain may allow information disclosure. System software 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 (high), integrity (none) and availability (none) impacts.
