Doc Text:
A flaw was found in the Intel Trust Domain Extensions (TDX) Migration Trust Domain (MigTD). The software fails to clear sensitive information from internal resources before releasing them for reuse. A local attacker with privileged system access could exploit this flaw to inspect uncleared memory, resulting in an information disclosure of confidential data.

Description OSIDB Bzimport 2026-11-10 19:52:46 UTC 
Sensitive information uncleared in resource before release for reuse in the MigTD for the Intel(R) TDX Migration Trust Domain (MigTD) within Ring 0: Hypervisor may allow an 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 not 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.
