Doc Text:	A flaw was found in Intel Trust Domain Extensions (TDX) Workload Attestation software. Improper certificate validation in user-space applications allows a local, unprivileged attacker to escalate privileges and tamper with sensitive data. An adversary can exploit this vulnerability without user interaction under specific conditions to compromise system integrity.	Story Points:	---

Description OSIDB Bzimport 2026-11-10 20:44:32 UTC

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.
