Name of the Vulnerable Software and Affected Versions TDX Module versions prior to tdx1.5

Description An out-of-bounds read issue exists within the hypervisor in some TDX Module versions prior to tdx1.5 when operating in Ring 0. A software side channel adversary with a privileged user, combined with a high complexity attack, may enable data exposure. This may occur via local access when attack requirements are present, without requiring special internal knowledge or user interaction. The issue may potentially impact the confidentiality of the vulnerable system.

Recommendations Update to TDX Module version tdx1.5 or later.
