# Intel TDX Workload Attestation: improper certificate validation lets local apps tamper data

Link for people: https://infrastack.ai/live/CVE-2026-42067 (this .md is for agents)

Some Intel TDX Workload Attestation software running in user space does not validate certificates properly. A local, unprivileged attacker can manipulate data and may escalate privileges on the vulnerable system.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

Improper certificate validation for some Intel(R) TDX Workload Attestation software within Ring 3: User Applications may allow an escalation of privilege. Unprivileged software adversary with an unauthenticated user combined with a low complexity attack may enable data manipulation. This result may potentially occur via local access when attack requirements are 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.
