MEDIUMCVSS 6.8/10

Last modified

CVE-2026-57893 is a medium-severity vulnerability rated 6.8/10 on the CVSS scale. Incomplete internal state distinction in the MigTD's SPDM responder for the Intel(R) TDX Migration Trust Domain (MigTD) within Ring 0: Hypervisor may allow an escalation of privilege. System software adversary with a privileged user combined with a low complexity attack may enable data corruption.

Description

Incomplete internal state distinction in the MigTD's SPDM responder for the Intel(R) TDX Migration Trust Domain (MigTD) within Ring 0: Hypervisor may allow an escalation of privilege. System software adversary with a privileged user combined with a low complexity attack may enable data corruption. This result may potentially occur via adjacent access when attack requirements are not present without special internal knowledge and requires no user interaction. The potential vulnerability may impact the confidentiality (none), integrity (high) and availability (none) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
