Intel R Tdx Modules
Monthly
Denial of service in Intel TDX (Trust Domain Extensions) modules at Ring 0 can be triggered by a system software adversary who already holds kernel-level privileges, causing an uncaught exception that crashes Trust Domain availability. Exploitation is constrained to local access with high attack complexity and specific attack prerequisites, meaning only highly privileged, sophisticated actors in TDX-enabled environments are realistic threat actors. No public exploit code or active exploitation (CISA KEV) has been identified at time of analysis, and the impact is limited strictly to availability - no confidentiality or integrity compromise is possible through this vector.
