Key Information:

Vendor

Intel
Status
Tdx Module May Allow An Escalation Of Privilege. System Software Adversary With A Privileged User Combined With A High Complexity Attack May Enable Escalation Of Privilege. This Result May Potentially Occur Via Local Access When Attack Requirements Are Not Present Without Special Internal Knowledge And Requires No User Interaction. The Potential Vulnerability May Impact The Confidentiality (high), Integrity (low) And Availability (none) Of The Vulnerable System, Resulting In Subsequent System Confidentiality (none), Integrity (none) And Availability (none) Impacts.

Affected Version(s)

TDX Module may allow an escalation of privilege. System software adversary with a privileged user combined with a high complexity attack may enable escalation of privilege. This result may potentially occur via local access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (high), integrity (low) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
