Intel MigTD SPDM Responder Information Disclosure Vulnerability
Description
Improper cleanup on thrown exception in the MigTD's SPDM responder for the Intel(R) TDX Migration Trust Domain (MigTD) within Ring 0: Hypervisor may allow an information disclosure. Network adversary with an unauthenticated user combined with a low complexity attack may enable data exposure. This result may potentially occur via network 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 (none), integrity (none) and availability (none) impacts.
