No structured fix or guidance is available here. Check the latest publisher advisory.

What this means

The Intel(R) TDX Migration Trust Domain (MigTD) hypervisor may allow a denial of service. A network adversary with low complexity attack may enable this. The vulnerability may impact system availability.

Summarized by @cf/meta/llama-3.3-70b-instruct-fp8-fast. Verify details against the original sources.

Original source description

Read the full publisher description

Incorrect behavior order in the get_tcb_level_by_svn for the Intel(R) TDX Migration Trust Domain (MigTD) within Ring 0: Hypervisor may allow a denial of service. Network adversary with an unauthenticated user combined with a low complexity attack may enable denial of service. 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 (none) and availability (low) of the vulnerable system, resulting in subsequent system confidentiality (none), integrity (none) and availability (none) impacts.
