Name of the Vulnerable Software and Affected Versions Intel TDX versions prior to 1.5.05.46.698

Description The issue is related to improper input validation in some Intel TDX module software, which may allow a privileged user to potentially enable escalation of privilege via local access. This could permit an attacker to increase their privileges.

Recommendations For versions prior to 1.5.05.46.698, update to version 1.5.05.46.698 or later to resolve the issue. As a temporary workaround, consider restricting local access to minimize the risk of exploitation.
