High severity with no evidence of exploitation so far.

What to do

  1. Check which version of Intel(R) TDX Migration Trust Domain (MigTD) you run against the affected versions below, and install the vendor's latest release.
  2. Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official 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.

The underlying weakness: Improper Cleanup on Thrown Exception

The product does not clean up its state or incorrectly cleans up its state when an exception is thrown.

How developers prevent this class of flaw

  • If one breaks from a loop or function by throwing an exception, make sure that cleanup happens or that you should exit the program. Use throwing exceptions sparsely.
