CVE-2026-20775 - Vulnerability Details

- Intel TDX Modules Uncaught Exception Leading to Denial of Service

Description

Uncaught exception for some Intel(R) TDX modules within Ring 0: Trust Domain may allow a denial of service. System software 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 (high) impacts.

Analysis

Impact

An uncaught exception can occur in some Intel TDX modules within Ring 0, leading to a denial of service. The vulnerability affects availability only, with no impact on confidentiality or integrity, and is classified under CWE-248.

Affected Systems

Intel TDX modules, version details are not provided.

Risk and Exploitability

The CVSS score of 6.8 indicates a moderate severity for availability. The EPSS score of less than 1% suggests a very low probability of exploitation. The vulnerability is not listed in the CISA KEV catalog. Likely exploitation requires a local attacker with privileged user access, a high complexity attack, and no special internal knowledge or user interaction. Once exploited, the affected system could become unavailable due to a crash of the Trust Domain.

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).

Description		Uncaught exception for some Intel(R) TDX modules within Ring 0: Trust Domain may allow a denial of service. System software 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 (high) impacts.
